Question

a demainsion of cuboide are the ratio 3:2:1 and the total surface area is 5632 cm square. Find the volume​

Answer 1

Let L be 3x , B be 2x , H be x

Surface area = 2( lb + bh + hl )

》 5632 / 2 = 6x^2 + 2x^2 + 3x^2

2816 = 11x^2

x^2 = 256

x = 16

L = 3 × 16 = 18

B = 2 × 16 = 32

H = 16

Volume = ( 18 × 32 × 16 ) cm3
