Chapter SR19, Problem 3P

Solution

Find the surface area and volume of the solid.

The surface area of cube $=54c{m}^2$

The volume of cube $=27c{m}^3$

Given:

The given solid.

  

Concept Used:

• Formula of surface area of cube $=6a^2$ .
• Formula of volume of cube $=a^3$

Calculation:

The given solid is -

  

As the given solid is cube.

The surface area of cube $=6a^2$

  $\begin{array}{l}$ =6{(3)}^2$=6(9)\\ =54\end{array}$

So, The surface area of cube $=54c{m}^2$

The volume of cube $=a^3$

  $\begin{array}{l}$ ={(3)}^3$=27\end{array}$

So, The volume of cube $=27c{m}^3$
