Question

the breath of a room is twice it's height one half of its length the volume of room is 512cubic m find its dimensions​

Answer 1

Step-by-step explanation:

Let, height=x

Breadth=2x

Length=4x

so, Volume= 512 cubic meters

or, l x b x h = 512

or, (4x)x(2x)x(x)=512

or, 8x^3 =512

or, x^3=512/8

=64

or, x= cube root of 64= 4

or, Length= 4x =4x4 =16m

Breadth= 2x = 2x4= 8m

Height= x = 4 m
