PLS I NEED HELP!!! If Mary Can Paint 1/4 Of A Wall In 20 Minutes, How Long Will It Take Her To Paint

Answers

Answer 1

Answer:

80 minutes

Step-by-step explanation:

One wall takes 20 minutes, so 20×4=80 minutes.

Answer 2

Answer: 320 minutes

Step-by-step explanation:

1/4 of a wall takes 20 minutes, therefore one wall takes 80 minutes. Multiply that by 4 for 4 walls, and that becomes 320 minutes.

The base of the rectangular prism is shaded. What is the lateral surface area?

Answers

Answer:

The answer is 126.

Step-by-step explanation:

Height equals 4.5.

Perimeter is 11 + 3 + 11 + 3 = 28

The formula is s = ph

Perimeter times Height.

28 time 4.5 is 126.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangular surface. Then the lateral surface area is 192 square ft.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangular surface.

The dimensions of the rectangular prism are as;

Height = 4.5 ft

Length = 11 ft

Width = 3 ft

Then the lateral surface area will be

[tex]\rm lateral\ surface\ area = area\ of \ each \ face\\\\lateral\ surface\ area = 2*(4.5*11 + 11*3 + 3*4.5)\\\\lateral\ surface\ area = 2*(49.5 + 33+13.5)\\\\lateral\ surface\ area = 2*96\\\\lateral\ surface\ area = 192[/tex]

Thus, the lateral surface area is 192 square ft.
