A rectangular solid has sides of 4 cm, 6 cm, and 8 cm. What is its surface area?

Solution:

Given, a rectangular solid of sides 4cm, 6cm and 8cm.

We have to find the surface area of a rectangular solid.

The surface area of a rectangular solid is given by

A = 2(xy + yz + zx)

Where, x, y and z are the dimensions of the rectangular solid.

Here, x = 4, y = 6 and z = 8.

Surface area, A = 2[(4 × 6) + (6 × 8) + (8 × 4)]

A = 2[24 + 48 + 32]

A = 2[104]

A = 208 square centimeters.

Therefore, the surface area of rectangular solid is 208 square centimeters.

A rectangular solid has sides of 4 cm, 6 cm, and 8 cm. What is its surface area?

Summary:

A rectangular solid has sides of 4cm, 6cm and 8cm. Its surface area is 208 square centimeters.
