Question

What is the surface area of a rectangular brick with a length of 12 in, a width of 8 in, and a height of 6 in?

Answer 1

Answer:

We can apply the formula for surface area of a rectangular prism here. i.e.

Step-by-step explanation:

A=2(l×w + h×l + h×w), where l is length, h is height and w is width.

As mentioned above, length = 12 cm, width = 8 cm and height = 6 cm.

Therefore

2(12×7+6×12+6×8)=2(84+72+48)=2(204)=408. So the surface area of the brick is 408 square centimetres.
