Answer:
The volume of the pyramid in cubic millimeters is 1890 mm³
Step-by-step explanation:
To calculate the volume of a rectangular pyramid in cubic millimeters with a base 21 millimeters by 18 millimeters and a height of 15 millimeters, we will follow the steps below:
First, write the formula for calculating the volume of a rectangular pyramid
v = [tex]\frac{lwh}{3}[/tex]
where v is the volume of the rectangular pyramid
l is the base length
w is the base width
and h is the pyramid height
From the question given
height h = 15 millimeters
l = 21 millimeters and w= 18 millimeters
we can now proceed to insert the values into the formula
v = [tex]\frac{lwh}{3}[/tex]
v = 21 × 18× 15 /3
v =[tex]\frac{5670}{3}[/tex]
v = 1890 mm³
Therefore, the volume of the pyramid in cubic millimeters is 1890 mm³
