\qquad \sf  \dashrightarrow \:2 {x}^{2}  - 4 {x}^{2}  + 5x + 6x - 7 + 3

What is the total surface area of the square pyramid?
pochemuha

Answer:

48

Step-by-step explanation:

The square pyramid has exactly the same four triangles.

In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.

Surface area of square pyramid = \frac{bh}{2} * 4

Where we know that b = 4 and h = 6.

Substituting into the formula should give us the answer 48.
