What is the surface area of the rectangular prism below?
Andrew [12]

Answer:

B ( 432 units^2)

Step-by-step explanation:

Total surface area= 2*(6*6)+ 4*(15*6)

There are 2 squares at each end of the same size so total area will be 2*(6*6)

If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)

In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2

Express 5 quarts to 5 gallons as a fraction in simplist form. Show work.
Anettt [7]

Answer:

1/4

Step-by-step explanation:

To express 5 quarts to 5 gallons as a fraction in simplest form, find the relationship between quarts and gallons.

1 quarts = 0.25 gallons

5 quarts = 5 × 0.25 gallons

              = 1.25 gallons

Therefore, 5 quarts to 5 gallons is equivalent to 1.25 gallons to 5 gallons

= 1.25/5 = 125/500

= 1/4 in the simplest form
