2160ft3

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
