Answer:
To find the volume of a rectangular pyramid, you can use the formula:
V= 1/3×base area×height
First, let's calculate the base area of the rectangular pyramid. Since the base of the pyramid is a rectangle, the area is given by:
Base Area=length×width
Given that the dimensions of the rectangular base are 9mm and 10mm, we have:
Base Area=9mm×10mm=90mm
Now, let's find the volume using the formula:
V= 1/3×90mm² × 10mm
²V= 1/3×900mm³
V=300mm³
So, the volume of the rectangular pyramid is 300mm³.
