The surface area of this cuboid is______ Square decimeter, volume is______ Cubic decimeter

The surface area of this cuboid is______ Square decimeter, volume is______ Cubic decimeter

Surface area: 1 × 1 × 10 = 10 (square decimeter), volume: 1 × 1 × 2 = 2 (cubic decimeter); answer: the surface area of this cuboid is 10 square centimeter, volume is 2 cubic centimeter

A cuboid with a surface area of 360 square centimeters can be cut into two identical cubes. How many cubic centimeters is the volume of each small cube?

360 ÷ (4 × 2 + 2), = 36 △ 10, = 36 (square centimeter), because 6 × 6 = 36, so the edge length of the cube is 6cm, then the volume of the cube is: 6 × 6 × 6 = 216 (cubic centimeter), a: the volume of each small cube is 216 cubic centimeter

A square steel with an edge length of 0.4 meters is forged into a cuboid square steel with a cross-sectional area of 0.04 square meters
How to do the fourth question on page 17 of Jiangsu Education Edition

Volume of square steel with edge length of 0.4m
=0.4 ^ 3 = 0.064 m3 = volume of cuboid square steel
Length of rectangular square steel = 0.064 △ 0.04 = 1.6m
