Question

Find the total surface area of the figure below.

Answer 1

37.5 cm²

Explanation:

Given:-

• Side of cube :- 2.5cm

To find:-

• Total Surface Area

Solution:-

Total surface area of cube :- 6a²

6(2.5)² sq. cm

37.5 cm²

Answer 2

• 37.5 sq.cm

⠀

Explanation:

⠀

We know,

`{\longrightarrow \qquad \boldsymbol{\pmb{Total \: \: surface \: \: area_((cube)) = 6a {}^(2) }}}`

⠀

Where,

• a is the side length of the cube. Here, a = 2.5 cm

⠀

Now, Substituting the values in the formula :

⠀

`{\longrightarrow \qquad \rm{{Total \: \: surface \: \: area_((cube)) = \sf 6 *( 2.5) {}^(2) }}}`

⠀

`{\longrightarrow \qquad \rm{{Total \: \: surface \: \: area_((cube)) = \sf 6 *6.25 }}}`

⠀

`{\longrightarrow \qquad \boldsymbol{ \pmb{Total \: \: surface \: \: area_((cube)) = \it 37.5 }}}`

⠀

Therefore,

• Total surface area of the cube is 37.5 cm²
