The volume of a cube is 3944.312 cm³. find the length of a side. round your answer to the nearest 10th and write only the measurement 15.8 62.8 36.3 21.7

Volume is a cubic measurement of the length×width×height, and as the shape is a cube, then its height, width and length are equal. This means that the length of a side is cubed to get the volume, as all the side are the same length. So to find out the length of a side, do

To the nearest 10th, 15.8 is 20 as you round units from 5-9 upwards

The formula used will be:

tan 42° = y/115

Step-by-step explanation:

Lets simplify the the question.

We have a boat which is situated at 115 meters away from a light house. It forms the base of the right angled triangle.

We need to find the distance from the bottom of the light house to the top of the light house. This distance is the height of the lighthouse, which forms the perpendicular side of the right angled triangle.

The distance between boat and top of the lighthouse is unknown, it forms the hypotenuse.

The angle of elevation, which is the angle between base and hypotenuse, is given as 42°.

The right angled formed is shown below.

We know that

tanθ = Perpendicular / Base

tan42 = height / 115

If height= y

tan 42° = y/115

Solve for y.

y = 103.55 meters
