Arectangle prism has the dimensions 8 feet by 3 feet by 5 feet. what is the surface area of the prism

158 square feet

Step-by-step explanation:

The surface area of a prism is found using the following formula: SA = 2(lh+lb+bh). This formula takes the area of each face (6 in total( and adds them together to find a total sum. Substitute l = 8, b = 3 and h = 5 to solve for the surface area.

SA = 2(lh+lb+bh)

SA = 2(8*5+8*3+3*5)

SA = 2(40 + 24 + 15)

SA = 2(79)

SA = 158

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
