Question

How do you find the base area of a rectangular prism and a cylinder? Please help

Answer 1

See explanation.

Explanation:

The 'base' of a rectangular prism refers to only one side of the rectangular prism, which is a rectangle.

The formula for the area of a rectangle is as follows:

`A=lw`

Where A = area, l = length, and w = width.

The 'base' of a cylinder refers to only one side of the cylinder, which is a circle.

The formula for the area of a circle is as follows:

`A=\pi r^2`

Where A = area and r = radius.

Just in case you typed your question incorrectly and were asking for surface area, here is the formula for surface area for both as well:

Rectangular prism:
`A=2(wl+hl+hw)\\`

Cylinder:
`A=2\pi rh+2\pi r^(2)`
