Question

A total surface area of cube whose side measure 5 cm is
(a) 25 cm 2
(b) 125 cm 2
(c) 150 cm2
(d) 100 cm2​

Answer 1

Total surface area of cube = 6a²

= 6×(5)²

= 6×25

= 150cm²

This is your answer

c) 150cm ²

Answer 2

$\LARGE{ \underline{\underline{ \pink{ \bf{Answer}}}}}$

T.S.A of cube = 150 cm²

Step-by-step explanation:

We know that to Find T.S.A of Cube We use the Formula :-

• $\tt{T.S.A = 6a^2}$ where ''a'' is the edge or side of the cube .

• $\tt{T.S.A = 6 \times 5^2}$

• $\tt{T.S.A = 6 \times 25}$

• $\tt{T.S.A = 150 cm^2}$
