Question

find the volume of a cuboid whose breadth is half of its length and height is double the length​

Answer 1

let length be l. then,

length =l

breadth =l/2

and height =2l.

volume =l*b*h

=l*l/2*2l

=l^3

Answer 2

Soln- Let Length be x.

Then, breadth= 1/2x

And height= 2x

We will substitute the values. For instance lets take x as 5cm.

Then breadth= 1/2 x 5 = 2.5cm

And height = 2 x 5= 10cm

Volume = length x breadth x height

= 5 x 2.5 x 10

= 125cm3
