Two similar triangular prisms have volumes of 27 square meters and 64 square meters.
Inessa [10]

Answer:

9/16

Step-by-step explanation:

First we need to know that the dimensions ratio, the surface area ratio and the volume ratio have the following relation:

volume ratio = dimension ratio ^3

surface area ratio = dimension ratio ^2

The volume ratio between small prism and the large prism is 27 / 64.

To find the dimensions ratio, we need to take the cubic root of the volume scale:

dimension ratio = 3√(27/64) = 3/4

Now, to find the surface area ratio, we just need to make the square of the dimension ratio:

surface area ratio = (3/4)^2 = 9/16

Write a problem that by comparing feet and inches using a model.include a solution. Explain why are you changing from a larger u
ziro4ka [17]

Change 4 feet to inches.

You need to know that for every feet, there are 12 inches. So, if you have 4 feet, you just multiply 4 by 12 and you will get 48 inches. Note that the feet unit is larger than inches.
