What is the surface area of the right prism? height-18in, width-6in, length-9in
possible answers-
a-648
b-972
c-486
d-540

Option A.

Step-by-step explanation:

The surface area of a right rectangular prism can be calculated with this formula:

Where "w" is the width. "l" is the lenght and "h" is the height.

We know that:

Knowing this values, we can substitute them into the formula.

Therefore we get that the surface area of a right rectangular prism is this:

This matches with the option A.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is
