Question

If one pint of paint covers 200 square inches how many pints of paint do I need to purchase the paint is only sold in whole pints The height is 6 in the width is 8 in the face is 19 in and the length is 10 in

Answer 1

First, calculate the total surface area of the object by adding together the areas of each face:

Face 1 (height x width): 6 in x 8 in = 48 sq in
Face 2 (height x width): 6 in x 8 in = 48 sq in
Face 3 (face x height): 19 in x 6 in = 114 sq in
Face 4 (face x height): 19 in x 6 in = 114 sq in
Face 5 (length x height): 10 in x 6 in = 60 sq in
Face 6 (length x height): 10 in x 6 in = 60 sq in

Total surface area: 48 sq in + 48 sq in + 114 sq in + 114 sq in + 60 sq in + 60 sq in = 444 sq in

Since one pint of paint covers 200 square inches, divide the total surface area by 200 to find out how many pints of paint you need:

444 sq in / 200 sq in = 2.22 pints

Since paint is sold in whole pints, you will need to purchase 3 pints of paint to cover the entire object.
