Respuesta :
Answer: the length of the altitude is 10 mm
Step-by-step explanation:
The formula for determining the volume of a square base pyramid is expressed as
Volume = Ah
Where
A represents the area of the square base.
h represents the height or altitude of the pyramid.
From the information given,
Length of each side of the square base = 2 millimeters
Volume of the square pyramid is 40 cubic.
Area of square base = 2² = 4 mm²
Therefore,
40 = 4h
h = 40/4
h = 10 mm
