Answer:

The least amount of fabric are 22 square feet

Step-by-step explanation:

we know that

The surface area of a rectangular prism is given by the formula

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

Let

L ---> the length pf the prism

W ---> the width of the prism

H ---> is the height of the prism

Let

L=2\ ft\\W=3\ ft\\H=1\ ft

Find the area of the base

B=LW=(2)(3)=6\ ft^2

Find the perimeter of the base

P=2(L+W)=2(2+3)=10\ ft

Find the surface area

SA=2(6)+10(1)=22\ ft^2

therefore

The least amount of fabric are 22 square feet

The first one we need to find the slope

m = (y2-y1)/(x2-x1) = (40-0)/(4-0) =40/4 = 10 minutes per mile

The second  is 8.5 minutes per mile

The third we need to find the slope

m = (y2-y1)/(x2-x1) = (90-72)/(10-8) =18/2 = 9 minutes per mile

Can u guys pls help me on this question and pls explain how u got the answer
Lady_Fox [76]

Answer:

55.75

Step-by-step explanation:

find the area of 1 side using the base and height and divide that answer by 2

5x6=30     30 divided by 2=15

all sides are equal so each side is 15

the base you do the same thing.

base is 5, height is 4.3

4.3 x 5= 21.5

divide it by 2 10.75

side 1=15

side 2= 15

side 3=15

base 1= 10.75

add all together

55.75
