How many cubes can be put into a cuboid wooden box with a volume of (15 × 10 × 20) cubic centimeter at most?

15 △ 2 = 7 1 (CM), 10 ／ 2 = 5 (pieces), 20 ／ 2 = 10 (pieces), 7 × 5 × 10 = 350 (pieces); a: 350 cubes with 2 cm edge length can be installed at most

Two cubes of the same size are put together to form a cuboid. It is known that the total length of the edges of the cuboid is 48 cm, so the surface area of each cube is 40 cm______ Square centimeter

48 △ 16 = 3 (CM), 3 × 3 × 6 = 54 (square cm). Answer: the surface area of each cube is 54 square cm

Use three identical cubes to make a cuboid. Given that the sum of the edges of the cuboid is 40 cm, what is the volume of the cuboid

The sum of the edges of a known cuboid is 40 cm
If the cube edge length is 1
Then 1 × 4 × 2 + 3 × 1 × 4 = 20
40/20=2
The edge length is 2
2×3=6
2×2×6=24
Hope to help you!
