Question

If TSA of cube is 2400cm² then LSA of the cube is​

Answer 1

ANSWER:

Lateral surface area (LSA) of the given cube is 1600cm²

SOLUTION:

Given:

TSA ( total surface area) of cube is 2400cm².

A↓t = 2400 cm²

6a² = 2400

a² = 400

a = √400

a = 20cm

So the side length of the cube is 20 cm.

So the lateral surface area of the cube.

A↓t = 4a²

A↓t = 4(20)²

A↓t = 4(400)

A↓t = 1600 cm²

So , the lateral surface area of the given cube is 1600 , cm².
