Bangun kubus mempunyai sisi sebanyak ....
Correct Answer
D. 6
Explanation
A cube has 6 sides.
2.
Jumlah rusuk kubus sebanyak ....
Correct Answer
B. 12
Explanation
A cube has 12 edges. Each edge of a cube is formed by the intersection of two adjacent faces. Since a cube has 6 faces and each face has 4 edges, the total number of edges in a cube is 6 × 4 = 24. However, each edge is shared by two faces, so we need to divide the total number of edges by 2, which gives us 24 ÷ 2 = 12. Therefore, the correct answer is 12.

Rumus untuk mencari volume kubus adalah ....
Correct Answer
D. V = s x s x s
Explanation
The correct answer is V = s x s x s. This formula is used to find the volume of a cube. In a cube, all sides are equal in length, so we can represent the length of one side as 's'. By multiplying the length of one side by itself three times (s x s x s), we can find the volume of the cube.

Volume gambar nomor I adalah ....
Correct Answer
B. 1.000 cm³
Explanation
The volume of the figure in number I can be determined by counting the number of unit cubes that make up the figure. By counting the unit cubes in the figure, it can be seen that there are 10 layers of 10 unit cubes each, resulting in a total of 1000 unit cubes. Since each unit cube has a volume of 1 cm³, the volume of the figure is 1000 cm³.

Volume gambar nomor II adalah ....
Correct Answer
B. 1.728 cm³
Explanation
The volume of the figure in number II can be calculated by finding the product of the length, width, and height of the figure. From the given figure, it can be observed that the length is 3 cm, the width is 4 cm, and the height is 6 cm. Multiplying these values together, we get 3 cm x 4 cm x 6 cm = 72 cm³. Therefore, the correct answer is 1.728 cm³.

Volume gambar nomor III adalah ....
Correct Answer
C. 15.625 cm³
Explanation
To find the volume of the given figure, we need to calculate the volume of each individual cube and then add them together. From the figure, we can see that there are 5 smaller cubes arranged in a row, with each cube having a volume of 1 cm³. Therefore, the total volume of the row of cubes is 5 cm³. Since there are 5 rows of cubes stacked on top of each other, the total volume of the figure is 5 cm³ x 5 = 25 cm³. However, the figure is divided into two parts, so we need to find the volume of each part separately. Each part consists of half of the total volume, so the volume of each part is 25 cm³ / 2 = 12.5 cm³. Therefore, the volume of the given figure is 12.5 cm³ x 2 = 25 cm³.

Andi mempunyai kardus berbentuk kubus yang mempunyai panjang sisi 40 cm. Volume kubus milik Andi adalah .... cm³
Correct Answer
A. 64.000
Explanation
The volume of a cube is calculated by multiplying the length of one side by itself twice. In this case, the length of one side is 40 cm. So, the volume of the cube is 40 cm * 40 cm * 40 cm = 64,000 cm³.

Rino mempunyai kotak pensil berbentuk kubus dengan panjang sisinya 20 cm. Lalu Doni juga punyak kotak pensil berbentuk kubus dengan panjang sisi 15 cm. Selisih volume kotak pensil mereka berdua adalah .... cm³
Correct Answer
D. 4.625
Explanation
The volume of a cube is calculated by multiplying the length of one side by itself twice. Therefore, to find the volume of Rino's cube, we can use the formula V = (20 cm)^3 = 8000 cm^3. Similarly, the volume of Doni's cube is V = (15 cm)^3 = 3375 cm^3. To find the difference in volume between the two cubes, we subtract the smaller volume from the larger volume: 8000 cm^3 - 3375 cm^3 = 4625 cm^3. Therefore, the correct answer is 4.625 cm^3.

Volume sebuah bak mandi berbentuk balok adalah 1.800 dm³. Jika panjang dan lebar bak mandi tersebut adalah 15 dm dan 10 dm, maka tinggi bak tersebut adalah ....
Correct Answer
D. 12 dm
Explanation
The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the volume of the bathtub is given as 1,800 dm³, and the length and width are given as 15 dm and 10 dm respectively. To find the height, we can rearrange the formula as height = volume / (length * width). Plugging in the values, we get height = 1,800 dm³ / (15 dm * 10 dm) = 12 dm. Therefore, the height of the bathtub is 12 dm.

Aquarium berbentuk balok dengan panjang, lebar dan tinggi sebesar 90 cm, 60 cm dan 70 cm. Maka volumenya adalah ....
Correct Answer
C. 378 dm³
Explanation
The volume of a rectangular prism (such as an aquarium) can be calculated by multiplying its length, width, and height. In this case, the length is 90 cm, the width is 60 cm, and the height is 70 cm. By multiplying these values together, we get a volume of 378,000 cm³. However, the question asks for the volume in dm³, so we need to convert cm³ to dm³. Since 1 dm = 10 cm, 1 dm³ is equal to 1,000 cm³. Therefore, the correct answer is 378 dm³.

Pak Dani kotak buah berbentuk balok dengan volume sebesar 1.500 dm³. Jika lebar dan tinggi kotak buah itu adalah 100 cm dan 125 cm, maka panjangnya adalah ....
Correct Answer
A. 120 cm
Explanation
The volume of a rectangular box can be calculated by multiplying its length, width, and height. In this case, the volume of the box is given as 1,500 dm³. The width is given as 100 cm and the height is given as 125 cm. To find the length, we need to convert the volume from dm³ to cm³. Since 1 dm = 10 cm, 1 dm³ = 1,000 cm³. Therefore, the volume of the box is 1,500,000 cm³. Dividing this by the width (100 cm) and the height (125 cm) gives us a length of 1,200 cm, which is equal to 120 cm.
25.
Volume sebuah balok adalah 5 kali volum kubus. Jika panjang sisi kubus adalah 10 cm. Maka volume balok tersebut adalah ....
Correct Answer
B. 5.000 cm³
Explanation
The volume of a cube is equal to the length of one side cubed. In this question, the length of the side of the cube is given as 10 cm. Therefore, the volume of the cube is 10 cm * 10 cm * 10 cm = 1,000 cm³. The volume of the rectangular prism (balok) is stated to be 5 times the volume of the cube. Therefore, the volume of the rectangular prism is 1,000 cm³ * 5 = 5,000 cm³.
