Question

Find the volume of a cube whose total surface area is 150 sq. m

Answer 1

Hey there!!!

Thank u for your Question ,


let a be the side the cube
we have

Total surface area = 150 sq m

$6 {a}^{2} = 150 \: sq \: m \: \\ = > {a}^{2} \: = 25 \\ \\ = > a =5sq \: m$
volume of that cube , a^3 = 5×5×5

=> 125 m^3

Hope this helps u!!!

Answer 2

surface area of a cube is 6a^2
then b.t.p 6a^2 =150
a^2 =25
a=5
then volume is 5^3=125
