Question

Find the length of the edge of a cube whose total surface area is
150 sq. cm. Hence find its volume

PLEASE ANSWER FAST

Answer 1

Given,
T.S.A.= 150 cm²
So,
T.S.A.= 6a²
150= 6a²
25= a²
a= √25
a= 5 cm
Now,
Volume= a³= (5)³= 125 cm³

Hope this helps you!

______________________________________

》To find :

Length and volume

》Given :

Total surface area = 150 ${cm}^{2}$

》Solution :

TSA of cube = 6${a}^{2}$

150 = 6${a}^{2}$

25 = ${a}^{2}$

a = 5 cm

So, the length of the cube is 5 cm.

Now,

Volume = ${a}^{3}$

Volume = ${5}^{3}$

Volume = 125 ${cm}^{3}$

So, the volume of the cube is 125 ${cm}^{3}$ .
