Explanation:

Answer 2

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 =
`(1)/(2)*base*height`

Area of face =
`(1)/(2)*16*14=112`

Another face area =
`(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
