Kaitlin is constructing a box in the shape of a rectangular prism to hold her lab supplies. To sit on her locker shelf, she need

Basile [38]

Answer:

The box must be 3 inches in height

Step-by-step explanation:

In this question, we are concerned about calculating the height of the supplies box.

To be able to get the value for the volume, we need to use the mathematical formula.

Since It is a rectangular prism, the volume V = l * b * h

where l, b and h are the length, breadth and height respectively. Now , it is the measurement of the base that is l * b, hence the base area in this question is 6 * 5 = 30 inches^2

The height of the supply box is thus 90/30 = 3 inches high

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-1, -13)

Point (-1, 21)

Step 2: Find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(0)^2+(34)^2}$
[√Radical] Simplify: $\displaystyle d = \sqrt{(34)^2}$
[√Radical] Evaluate: $\displaystyle d = 34$
