Cade covered the outside of a box shaped like a rectangular prism with paper. the box is 3.5 feet long, 2.2 feet wide, and 4.1 feet high. what is the total surface area of this box?

The total surface area of this box is  62.14 square feet

Step-by-step explanation:

Given:

Length = 3.5 feet

Width  =  2.2 feet

Height =  4.1 feet

To Find:

The Surface area of the prism = ?

Solution:

The box is the shape of rectangular prism

Then the surface area of the prism = 2(lh +hw +wl)

Where

l is the length

w is the width

h is the height

Substituting the values

The surface area of the prism =

The surface area of the prism = 2(14.35 + 9.02 + 7.7)

The surface area of the prism = 2(31.07)

The surface area of the prism = 62.14 square feet

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
