sweet [91]

Answer: 90cm^3

Step-by-step explanation:

A rectangular prism is a three-dimensional solid.

A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.

You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (18cm^3).

Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:

V_{prism}=5*V_1

Where V_1 is the volume of one layer.

Substituting, you get:

V_{prism}=(5)(18cm^3)\\\\V_{prism}=90cm^3

Lamont works for an electric utility and is installing a 40 foot utility pole as shown. Lamont drills the anchor of a support ca
PIT_PIT [208]

Answer:

<em>Approximately 43 feet of minimum cable is needed. </em>

Step-by-step explanation:

This problem can be solved using Trigonometry and Pythagorean theorem. Pythagorean theorem applies on right-triangles (<em>which are known to have one 90° angle</em>). The theorem states that the square of the Hypotenuse is obtained by the squared sum of the other two sides of the triangle (i.e the two sides forming the 90° angle - with the hypotenuse side being across it as:

h^2=a^2+b^2           Eqn. (1)

where

h is the hypotenuse

a is a side

b is a side

<u>Now in this case, the utility pole must be perpendicular to the ground and the anchor being parallel to the ground, and a 90° angle formed between them. </u>Conclusively the cable length will be represented by the hypotenuse in a right triangle. So here we have a=40ft and b=15ft. Plugging in Eqn.(1) and solving for h we have:

h^2=40^2+15^2\\h=\sqrt{40^2+15^2} \\h=\sqrt{1600+225}\\ h=\sqrt{1825}\\ h=5\sqrt{73}\\ h=42.72ft

So we conclude that the minimum length of cable needed by Lamont is

≈43 feet (rounded up).
