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

  • The lateral surface area is 307.2 square cm
  • The total surface area is 451.2 square cm

How to determine the lateral surface area?

The given parameters are:

Base (b) = 12 cm

Slant height (l) = 12.8 cm

The lateral surface area is calculated using:

L = 2bl

So, we have:

L = 2 * 12 * 12.8

Evaluate the product

L = 307.2

How to determine the total surface area?

This is calculated using:

T = L + b^2

So, we have:

T = 307.2 + 12^2

Evaluate

T = 451.2

Hence, the total surface area is 451.2 square cm
