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
