Volume of a pyramid with a square base of length 5m is 75m³. Find it's hieght​

The height of the pyramid is 3 m.

Step-by-step explanation:

Given;

volume of pyramid, V = 75 m³

length of the square, L = 5 m

The volume of a pyramid is given as;

V = area of the square base  x  height

V = Ah

where;

A = L² = 5 x 5 = 25 m²

h = V/A

h = (75) / (25)

h = 3 m

Therefore, the height of the pyramid is 3 m.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
