Question

Determine the lateral surface area and the total surface for the pyramid. Round your answer to the nearest whole number.

Separate your answers with a comma.

Answer 1

`L = 704`

`S = 832`

Explanation:

Given

`H = 22` --- Height

`W = 8` --- Width

`L=8` ---- Length

Solving (a): The lateral surface area (L)

This is calculated as:

`L = 2 * (L + W) * H`

This gives:

`L = 2 * (8 + 8) * 22`

`L = 2 * 16 * 22`

`L = 704`

Solving (b): The total surface area (T)

This is calculated as:

`S = 2 * (LW + WH + LH)`

This gives:

`S = 2 * (8*8 + 8*22+ 8*22)`

`S = 2 * (64 + 176+ 176)`

`S = 2 * 416`

`S = 832`
