A section of square steel is 4 decimeters long with a cross section of 25 square centimeters. How many cubic centimeters is the volume of this section of square steel?
4 decimeters = 40 cm
Volume = 40 * 25 = 1000 (CC)
A square billet with an edge length of 8 decimeters is forged into a rectangular square steel with a cross-sectional area of 0.16 square meters. How long is the square steel forged
Length = 0.8 × 0.8 × 0.8 △ 0.16 = 3.2m
A square steel block with an edge length of 1 decimeter is forged into a rectangular square steel with a cross-sectional area of 20 square centimeters. What is the length of this rectangular square steel
Centimeter?
Volume = 1 × 1 × 1 = 1 cubic decimeter = 1000 cubic centimeter
Length = 1000 △ 20 = 50cm
