The Fabric storage box below is shaped like a rectangular prism how much fabric is needed to cover the exterior of the box

Answer:

2952 square centimeters are needed to cover the exterior of the box.

Step-by-step explanation:

We need to cover five external faces of the box. The surface area formula (A_{s}), measured in square centimeters, is derived from surface area formula for parallelpiped:

A_{s} = w\cdot l + 2\cdot w\cdot h + 2\cdot l \cdot h (1)

Where:

w - Width, measured in centimeters.

l - Length, measured in centimeters.

h - Height, measured in centimeters.

If we know that w = 36\,cm, l = 23\,cm and h = 18\,cm, then the outer surface area of the storage is:

A_{s} = (36\,cm)\cdot (23\,cm)+2\cdot (36\,cm)\cdot (18\,cm)+2\cdot (23\,cm)\cdot (18\,cm)

A_{s} = 2952\,cm^{2}

2952 square centimeters are needed to cover the exterior of the box.

Solve the expressions on the left when x=5<br>3x-10<br>x^2-15<br>5x-21<br>x+10-8​
Nitella [24]

Answer:

5

10

4

7

Step-by-step explanation:

Apply the value of x into the expressions:

3(5) - 10 = 15 - 10

           = 5

5² - 15 = 25 - 15

          = 10

5(5) - 21 = 25 - 21

             = 4

5 + 10 - 8 = 15 - 8

               = 7
