The figure below is a diagram of a trapezoidal table that needs to be stained. each can of stain will cover 50 square inches.

if the table has an area of 350 square inches, how many cans of stain are needed to cover the table?

To find the number of cans needed, divide the total area by the area 1 can will cover:

350 / 50 = 7 cans are needed.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
