Example 7: Find the surface area of a cube whose side measures 5 cm. Also find its lateral
surface area.​

Answer 1

Answer:

Given, the side of a cube is 5 cm.

Total surface area of cube =6× (side) ^2

 

=6×5×5

=150

∴ The total surface area of cube is 150 cm ^2

.

Answer 2

✴Question:-

Find the surface area of a cube whose side measures 5 cm. Also find its lateral

Find the surface area of a cube whose side measures 5 cm. Also find its lateralsurface area.

________________________________

✴Solution:-

→Given:-

• Side of Cube=5cm

→To find:-

• Surface Area of Cube.
• Lateral Surface Area of Cube.

→Concept:-

• Simple measurement Problem.

→Formulas:-

• Surface Area of cube=${6a}^{2}$
• Lateral Surface Area=${4a}^{2}$

→Calculation:-

SurfaceArea=

${6a}^{2}\\=6×5×5\\=30×5\\={150cm}^{2}$

Lateral Surface Area=

${4a}^{2}\\=4×5×5\\=20×5\\={100cm}^{2}$

_______________________________

✴Final Answer:-

Hence,The Surface Area of Cube is ${150cm}^{2}$

And,Lateral Surface Area of Cube is ${100cm}^{2}$
