Question

if the edges of a cuboid are in the ratio 1:2:4 and its surface area is 21952 cm2,then the volume of the cuboid is. (ans- 175616)​

Answer 1

Step-by-step explanation:

let side be 1x 2x and 4x

2(lb+bh+lh) = 21952

(2x^2 + 8x^2 + 4x^2)= 21952/2

14x^2= 10946

x^2= 10976/14

x^2= 784

x=√784

x=28
