Question

The length of a cubiod is two times its breadth if its height and lateral surface area is 10 cm and 600 cm2 respective ly find its. volume?????????? one who gives the answer fast ill mark as a brainiest answer

Answer 1

let the length of the cuboid be
l,b,h
given that
2l =b
lateral surface area =2(lb+bh)
600 = 2(2l^2 + 20l)
300 = (2l^2 + 20l)
300 = 2(l^2+ 10l)
150= l^2+10l
l^2+10l-150 =0

now slove the equation you will get the value of l & b
after that find the volume
