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.

rectangle with a perimeter of 1110 meters, this rectangular shape is 30 meters longer than 6 times its width. find its dimension
Alecsey [184]

Answer:

The width of the rectangle is  75 meters and length is 480 meters.

Step-by-step explanation:

The perimeter of the rectangle = 1110 meters

Let the width of the rectangle = k meters

So,the length of the rectangle = 6k + 30

Now, PERIMETER OF A RECTANGLE = 2(LENGTH + WIDTH)

⇒ 1110 = 2( k + (6k + 30))

or, 1110 = 14 k + 60

or, 14 k = 1110 - 60 = 1050

⇒ k = 1050/14 = 75

Hence, the width of the rectangle is k =  75 meters

and the Length of the rectangle is 6k + 30 = 6(75) +30

= 480 meters
