Question

The breadth of a cuboid is 2less than its length and it's height is one less than its breadth. If the surface area of cuboid is188m. Find its volume.

Answer 1

Answer:

L=x

B=x-2

H=x-3

SA= 2(lb+bh+hl)=188

lb+bh+hl= 94

X*x-2+x-2*x-3+x-3*x= x^2-2x+x^2-3x-2x+6+x^2-3x

= 3x^2-10x+6= 94

3x^2-10x= 88

X= 14
