A rectangular prism measures 3ft by 6ft by 5ft. If the dimensions of the box were all quadrupled. How would the surface area of
Blababa [14]

The surface area of a shape is the amount of space on the shape

When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area

<h3>How to determine the surface area</h3>

The surface area of a rectangular prism is:

S = 2 * (lw + lh + wh)

When quadrupled, we have:

S_2 = 2 * (16lw + 16lh + 16wh)

Factor out 16

S_2 =16 * 2 * (lw + lh + wh)

Substitute S = 2 * (lw + lh + wh)

S_2 =16 * 2 * S

The above means that:

The new surface area would be 16 times the initial surface area

Assume that after t hours on the job, a factory worker can produce 100te^-.5t units per hour. How many units does the worker pro
VMariaS [17]
The number of units produced by the worker during t hours of work can be modelled by the following function:

N(t)=100t e^{(-0.5t)}

To find the number of units produced during first 3 hours, we can substitute 3 for t. This will give us the number of units produced by the worker during first 3 hours.

N(3)=100(3) e^{-0.5(3)} = 67

Thus the worker will produce 67 units during the first 3 hours of the work.
