Question

Find the surface area of a cube whose surface area is 600cm^2

Answer 1

Answer:

lateral surface area of cube=400cm²

Step-by-step explanation:

total surface area of cube =600cm²

total surface area of cube =6l²

600=6l²

600/6=l²

100=l²

l=10cm

lateral surface area of cube = 4l²

=4×10²

=4×100

=400cm²

Answer 2

Given:

• Total surface area of cube =600cm²

To find out:

Find the surface area of a cube.

Formula used:

• Total surface area of cube =6l²

• Lateral surface area of cube = 4l²

Solution:

Total surface area of a cube = 6l²

600=6l²

600/6=l²

100=l²

length,l=10cm

Now,

Lateral surface area of cube = 4l²

=4×10²

=4×100

=400cm²

EXTRA:

• Cuboid: Cuboid is a solid having six rectangular faces. It has 12 edges and 8 vertices.

• Cube: A cuboid in which length, breadth and height are all equal is called a cube. All the six faces of a cube are congruent square.
