Answer:

Area = 18 ft³   Surface Area = 44 ft²

Step-by-step explanation:

The formula for the area of a rectangular prism is A=lwh so you just plug in the numbers. For surface area, you have to find the area for each face and add them together.

What is the real number value of m^3+ √12 m when 5m^2 = 45 ?
babymother [125]
<h3>Answer: H. 33</h3>

=============================================

Work Shown:

Solve 5m^2 = 45 for m to get

5m^2 = 45

m^2 = 45/5

m^2 = 9

m = sqrt(9)

m = 3

I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.

--------------

Plug m = 3 into the expression we want to evaluate

m^3 + sqrt(12m)

3^3 + sqrt(12*3)

27 + sqrt(36)

27 + 6
