A cuboid is obtained by heightening a cuboid by 2cm (the bottom remains unchanged), and the surface area of the cuboid is 40cm larger than that of the original cuboid;,
Edge length 40 / 2 / 4 = 5cm
The original cube volume is 5 * 5 * 5 = 125 cubic centimeters
The surface area of a cuboid is 504cm, the perimeter of the bottom is 44cm, the area of the bottom is 120cm, and the volume of the cuboid is ()
The surface area of a cuboid is 504cm, the perimeter of the bottom surface is 44cm, the bottom area is 120cm, and the volume of the cuboid is 720 cubic centimeters
Length × width = 120cm & # 178;;
2 × (length + width) = 44 cm;
Length + width = 22 cm;
2 × (length × width + length × height + width × height) = 504 square centimeters;
Ψ height = (504 △ 2-120) △ 22 = 6cm;
Volume = 120 × 6 = 720 cm3;
