Answers for sheet # 193
1) lL x W x 20 cm = 500
L x W = 25 cm
L = W because carton is square
L = 5cm
W = 5 cm
There is only one combination.
No you can not design a carton with rectangular base having the volume 500 cubic centimeters and height 20 cm.
L x W should be equal to 25 sq cm. Only 5 x 5 = 25
