What is the surface area of this rectangular pyramid?

Answer 1

304 square meters

Explanation:

here is why,

area of a triangle formula is:

A = bh/2, so

12 * 10/ 2 = 60

we multiply this by two (for each triangle face with these dimensions) to get 120. then we do the same for the other two trangular faces.

8 * 11/2 = 44

we multiply by two again to get 88.

finally, for the base

12 * 8 because area of a rectangle formula is:

A = L * W

12 * 8 = 96

we get our final answer by adding everything up to get 96 + 88 + 120 = 304

Answer 2

Answer: ≈318.54

Area

Explanation:

A=lw+l
`√((w/2)^2+h^2+w)`
`√((l/2)^2+h^2)`
`12*8+12*√((8/2)^2+10^2+8) *√((12/2)^2+10^2) =318.54`
