What is the total surface area of the rectangular pyramid below?
Sergio [31]

Answer:

Step-by-step explanation:

Alright, lets get started.

The total surface area of rectangular pyramid will be the area of all four faces and area of base.

The faces are triangular, so area will be = \frac{1}{2}*base*height

Area of face = \frac{1}{2}*16*14=112

Another face area = \frac{1}{2}*12*15=90

Each face has its similar another face. So total area of faces will be = 112+112+90+90=404

Area of base = 12*16=192

So total surface area = 404+192=596 square feet

Hence the total surface area is 596 square feet.   :   Answer

Hope it will help :)
