Question

The total surface area of a cube is 96 cm. Find the length of the edge

Answer 1

Answer:

Given : T.S.A = 96 sqr cm.

We know, T.S.A of cube = 6a²

           

On substituting values, we get

6a²  = 96

 a² = 96 ÷ 6

 a = √16

 a = 4 cm

So length of edge of cube = 6 cm.

Answer 2

$\bigstar$ Question :

→ The total surface area of a cube is 96 cm. Find the length of the edge.

$\bigstar$ To Find :

→ Length of the edge = ?

$\bigstar$ Given :

→ Area of cube = 96 cm

$\bigstar$ Required Formula :

→ Total surface area of cube = 6a²

$\bigstar$ Solution :

Let,

  The length of the edge = a

→ Total surface area of cube = 96 cm

→ 96 = 6a²

→ a² = $\frac{96}{6}$

→ a² = 16

→ a = √16

→ a = 4 cm

∴ The length of the edge = a = 4 cm
