Question

The length , breadth , height of a cuboid are 4:3:2 . If its surface area is 2548 centimetre sq find its volume

Answer 1

Answer:

Step-by-step explanation:

let

l=4x........................(i)

b=3x.........................(ii)

h=2x............................(iii)

2(lb+bh+lh)=2548

2(12x^2+6x^2+8x^2)=2548

2(26x^2)=2548

26x^2=2548/2

26x^2=1274

x^2=1274/26

x=root of 49

x=7

from (i),(ii)and (iii)

l=28cm

b=21cm

h=14cm

volume = lbh

28*21*14=8232cm^3
