Stacy is covering the box below with sticky wrapping paper. If the paper cost 2 cents per square centimeter, how much will it cost to cover the entire box.

Given:

The shape of box is a right triangular prism.

Paper cost = 2 cents per square centimeter

To find:

The cost to cover the entire box.

Solution:

In the given right triangular prism, we have 3 rectangle surfaces and 2 triangular surfaces.

Area of a rectangle is

Area of rectangle with length 4 cm and width 3 cm is

Area of rectangle with length 4 cm and width 4 cm is

Area of rectangle with length 4 cm and width 5 cm is

Area of a triangle is

Area of triangle with base 3 cm and height 4 cm is

Bottom and top triangular surfaces are equal.

Now, total surface area of the box is

Paper cost = 2 cents per square centimeter

Cost of 60 square centimeter paper is

Therefore, the cost to cover the entire box is 120 cents or $1.2.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
