The rectangular prism shows a length of 5 cm and a height of 3 cm and a width of 4 cm what is the surface area of the prism

94 cm²

Step-by-step explanation:

The surface area of a rectangular prism is found by finding the surface area of each of the rectangular faces and adding them together.

l = length = 5 cm

w = width = 4 cm

h = height = 3 cm

SA = 2(lw) + 2(lh) + 2(wh)

SA = 2(5*4) + 2(5*3) + 2(4*3)

SA = 2(20) + 2(15) + 2(12)

SA = 40 + 30 + 24

SA = 70 + 24

SA = 94

The total surface area of the prism is 94 cm²

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
