Answer 1

The surface area of a triangle is defined as the area of the base added to the area of its four triangular faces. The area of the triangular face is going to be .5*(base)*(height) or .5(3)(6)=9 ft^2. This is multiplied by four for all the faces, so you have 36 ft^2. Finally, you have the area of the base, a square, which is just side^2. This is merely 3^2, which is 9 ft^2, so 36+9=45 ft^2.

Answer 2

\[SA=s^2+2sl\]

Answer 3

Okay so the answer is 36?

Answer 4

You tell us.

Answer 5

The answer is 45

Answer 6

Okay, I think I understand. Can you help me an a few more? Please?

Answer 7

SA = 1/2 perimeter of base times slant height + area of base
SA = 1/2 * 3*4*6 + 9
SA = ?
