Correct Answer
A. 91Explanation
The volume of a cube can be calculated by multiplying the length of one side by itself twice. In this case, the first rubik has a side length of 3 cm, so its volume is 3 cm * 3 cm * 3 cm = 27 cm^3. The second rubik has a side length of 4 cm, so its volume is 4 cm * 4 cm * 4 cm = 64 cm^3. Therefore, the volume of the second rubik is 64 cm^3.Rate this question:

Correct Answer
B. 341Explanation
The volume of a cube can be found by cubing the length of its side. In this case, the first cake has a side length of 6 cm, so its volume is 6^3 = 216 cm^3. The second cake has a side length of 5 cm, so its volume is 5^3 = 125 cm^3. To find the total volume of both cakes, we add the volumes together: 216 cm^3 + 125 cm^3 = 341 cm^3. Therefore, the correct answer is 341.Rate this question:

Archer membeli balok kayu berbentuk kubus dengan rusuk 20 cm. Kemudian dia memotongnya sepanjang 5 cm. Volume balok kayu Archer sekarang adalah ... cm3.
Correct Answer
7875Explanation
When Archer buys a wooden cube with a side length of 20 cm, the initial volume of the cube is calculated by multiplying the length, width, and height, which are all 20 cm. The resulting volume is 8000 cm3. However, Archer then cuts off a 5 cm section from one side of the cube. This reduces the length of each side to 15 cm. To calculate the new volume, we multiply the new side length by itself three times (15 x 15 x 15), which equals 3375 cm3. Therefore, the correct answer is 3375 cm3.Rate this question:

C. 64Explanation
The given question describes a scenario where instant noodle boxes are stacked in a cubic formation in a storage warehouse. It states that there are 8 boxes on each side of the cube and each box has a side length of 0.5 m. To find the volume of the cube, we need to calculate the total number of boxes in the cube and then multiply it by the volume of each box. Since there are 8 boxes on each side of the cube, the total number of boxes in the cube is 8 x 8 x 8 = 512. Since each box has a side length of 0.5 m, the volume of each box is 0.5 x 0.5 x 0.5 = 0.125 m³. Therefore, the volume of the cube made up of these boxes is 512 x 0.125 = 64 m³.Rate this question:

- A.
279
- B.
729
- C.
689
- D.
829
Correct Answer
B. 729Explanation
Zaka wants to put the rubiks cubes into a large cube-shaped box with sides measuring 0.9m. To find out how many rubik's cubes can fit in the box, we need to calculate the volume of the box and the volume of one rubik's cube. The volume of the box is calculated by multiplying the length of one side by itself three times (0.9m x 0.9m x 0.9m = 0.729m³). The volume of one rubik's cube is calculated by multiplying the length of one side by itself three times (0.1m x 0.1m x 0.1m = 0.001m³). To find out how many rubik's cubes can fit in the box, we divide the volume of the box by the volume of one rubik's cube (0.729m³ / 0.001m³ = 729). Therefore, the correct answer is 729 rubik's cubes.Rate this question:
