Think about a really long, flat 3-dimensional object. This has a certain volume, and a certain (big) surface area because of its length. Now, make the 3-dimensional object fat and maintain the volume. Notice how you have minimized surface area but maintained volume. This is how I would go about solving it.
Answer:
12 cans
Step-by-step explanation:
->link is 54 feet and it's width is 30 feet
Therefore,
Area = 54 x 30 = 1620ft²
Supposing each can of wood stain covers 135 ft.²
In order to find that how many cans will he need to cover the port, we'll divide the area of core by the area of each can of wood stain.
so,
= 12 cans
Therefore, he'll need 12 cans to cover the port.
Yes 1/4 is a rational number
The triangular prism has a volume of
.. V = Bh = (1/2)*(4ft *8 ft)*(24 ft) = 384 ft^3
