Question

A rectangular body has dimensions x and y (l & b). if it's dimensions get double what will happen to its volume?​

Answer 1

Suppose the dimensions of a rectangular solid is 1 then

V $=$ 1 $×$ 1 $×$ (l $×$ b $×$ h taken as 1)

V $=$ $1^3$

If it is doubled, then

V $=$ $2^3$

V $=$ 8 times

Hence volume will increase by 8 times.

Answer 2

Answer:

Suppose the dimensions of a rectangular solid is 1 , then

V = 1×1× ( l×b×h taken as 1 )

V = 1³

If it is doubled , then

V = 2³

V = 8times

Hence , volume will increase by 8 times !
