The areas of the square pyramid are the amount of space on it

  • The lateral surface area is 292.5 square cm
  • The total surface area is 354.85 square cm

How to determine the lateral surface area?

The given parameters are:

Base (b) = 15 cm

Slant height (l) = 13 cm

The lateral surface area is calculated using:

L = 1.5bl

So, we have:

L = 1.5 * 15 * 13

Evaluate the product

L = 292.5

How to determine the total surface area?

This is calculated using:

T = L + 0.25√3b^2

So, we have:

T = 292.5 + 0.25√3 * 12^2

Evaluate

T = 354.85

Hence, the total surface area is 354.85 square cm
