Question

Plz help thanks! Arusha draws a rectangular prism that is made up of two connector cubes each with edge length e. The surface Area of the rectangle prism is represented by the formula SA=10e^2 and the volume of the prism is represented by the formula V= 2e^3. What is the surface area of the prism is the edge length of each connector cube is 5 cm?

Answer 1

Answer:

Step-by-step explanation:

The SA would be 10e² because there are 10 squares.

The V would be 2e³ because there are 2 cubes.

Part A

If e = 5 cm, simply plug it into the SA formula we have already.

SA = 10e² = 10*5² = 10*25 = 250 cm².

Part B

If e = 5cm, simply plug it into the V formula we have already.

V = 2e³ = 2*5³ = 2*125 = 250 cm³.

Now we need to find what percent of 250 is 150?

250p = 150

p = 150/250 = 3/5 = 0.6 = 60%
