A cuboid wood block, cut from the top of the cuboid 5 cm high, the rest is a cube, the surface area reduced by 120 square centimeters______ Cubic centimeter

A cuboid wood block, cut from the top of the cuboid 5 cm high, the rest is a cube, the surface area reduced by 120 square centimeters______ Cubic centimeter

The original cuboid's length and width are: 120 △ 4 △ 5, = 30 △ 5, = 6 (CM); the original cuboid's height is: 6 + 5 = 11 (CM); the original cuboid's volume is: 6 × 6 × 11 = 396 (cm3); answer: the original cuboid's volume is 396 cm3. So the answer is: 396

For a cuboid, its height is reduced by 5cm, so it is a cube. At this time, its surface area is reduced by 120cm2. How many cubic centimeters is the volume of the original cuboid?

The length of cube is 120 △ 5 △ 4 = 6cm
Cuboid Volume 6 × 6 × (6 + 5) = 396 cubic centimeters

How many decimeters is the sum of all its edges and how many square decimeters does it cover

The sum of all the edge lengths is (5 + 3 + 4) × 4 = 12 × 4 = 48 decimeters
Floor area: 5 × 3 = 15 square decimeters
