Question

Find the surface area of cube whose side measure 5cm .Also find its lateral surface area.​

Answer 1

Given

• Side of cube = 5cm

To find

• Total surface area
• Lateral surface area

Solution

As we know that

→ Total surface area of a cube

→ 6a²

→ 6 × (5)²

→ 6 × 25

→ 150cm²

Now, Lateral surface area of cube

→ 4a²

→ 4 × (5)²

→ 4 × 25

→ 100cm²

Hence,

• Total surface area of cube = 150cm²
• Lateral surface area of cube = 100cm²

$\huge\bold{\underline{\underline{{Answer:-}}}}$

We know that:

Total surface area of the cube = 6(edge)²

$\huge{\boxed{\rm{\red{Given:-}}}}$

side = 5 cm

So, = 6(5)²

➣ 6 × 25

➣ 150 cm²

We also know that:-

Lateral surface area of the cube = 4(edge)²

Given, side = 5 cm

So, = 4(5)²

➣ 4 × 25

➣ 100 cm²

Therefore, the Total Surface Area of the given cube is 150 cm² and the Lateral Surface area of the cube is 100cm²
