Question

The dimension of cuboid are in ratio 4 ratio 2 ratio 1 and total surface area is to 2800 metre square find its volume

Answer 1

Step-by-step explanation:

let l=4x ,b =2x, h=1x

2(lb +bh+hl) =2800m square

2( 4x*2x + 2x*1x + 1x*4x) =2800

14 x square =1400

x square = 100

x = 10 m

l=4x=4*10=40 m

b=2x=2*10=20 m

h=10m

volume of cuboid = l*b*h

=40 *20*10

= 8000 answer
