Question

the volume and a total surface area of a cube whose each edge is 1.2m are
options
Vol.=1.728, T.S.A= 1.44
Vol.=1.728, T.S.A= 8.44
Vol.=1.728, T.S.A= 8.64
Vol.=8.64, T.S.A= 1.728

plss do this question step by step for me plssssss

Answer 1

Step-by-step explanation:

volume = ?

t.s.a=?

Given,

l= 1.2m

We know that,

$volume \: of \: cube \: = {a}^{3}$

$= 1.2 \times 1.2 \times 1.2$

$= 1.728 {m}^{3}$

We know that,

$total \: surface \: area \: of \: cube = 6 {a}^{2}$

$= 6 \times 1.2 \times 1.2$

$= 8.64 {m}^{2}$

therefore , option 3 is correct.

I hope it may help you .
