Question

The length, breadth and height of
a cuboid are in the ratio 5 : 3:2
and its total surface area is 6200
cm2. Find the valume of the cuboid in m3​

Answer 1

Answer:

2.4E8

Step-by-step explanation:

Let l= 5x b= 3x and H= 2

then

TSA= 6200 cm²

= 5x.3x + 3x.2x+ 2x.5x= 6200

= 15x²+ 6x²+ 10x²= 6200

= 31x²= 6200

x²= 200

Now l = 5x = 5 x 200= 1000

b= 3x = 3 x 200= 600

h= 2x= 2 x 200= 400

volume= L x B x H

1000x600x400

= 240000000
