Question

What is the surface of rectangular prism with the length 5cm, width 4cm and hight 2cm

Answer 1

Answer:

There are 6 surface areas, but we need

to calculate only 3 because:

The Front and Back are equal.

The Left and Right are equal.

The Top and Bottom are equal.

So we multiply each calculation by 2:

As = 2(4*3) + 2(5*3) + 2(4*5),

As = 24 + 30 + 40 = 94cm^2.
