1.	A solid box ,15 cm by,20 cm by 8 cm a new solid is format by removing cube 3 cm what percent original volume removed
Answer» Volume of larger cuboid = L x B x H L = 20 cm B = 15 cm H = 8 cm Volume = 20 x 15 x 8 = 2400 cubic cm Volume of cube = A x A x A A = 3 cm Volume = 3 x 3 x 3 = 27 cubic cm %removed = (27/2400) *100 = 2700/2400 = 9/8 = 1.125% So 1.125 % of original volume has been taken out

A solid box ,15 cm by,20 cm by 8 cm a new solid is format by removing cube 3 cm what percent original volume removed

Answer»

Volume of larger cuboid = L x B x H

L = 20 cm

B = 15 cm

H = 8 cm

Volume = 20 x 15 x 8 = 2400 cubic cm

Volume of cube = A x A x A

A = 3 cm

Volume = 3 x 3 x 3 = 27 cubic cm

%removed = (27/2400) *100 = 2700/2400 = 9/8 = 1.125%

So 1.125 % of original volume has been taken out
