This equation can be obtained simply by multiplying the three dimensions of the cube.
Length = x + 4
Width = 2x
Height = x
Volume = (x + 4)(2x)(x)
450 = 2x³ + 8x²
Using a graphing calculator and plotting this, we see that the solution of this equation is 5.
Therefore, the original side was 5 inches. The answer is B

The unknown sides of the right angle triangle using trigonometric ratios are as follows;

PR = 13.2 units

RQ = 17.6 units

<h3>What is a right angle triangle?</h3>

A right angle triangle is a triangle that has one of its angles as 90 degrees.

The sides of the triangle can be found using trigonometric ratios.

Therefore,

sin 37° = opposite / hypotenuse

sin 37° = PR / 22

cross multiply

PR = 22 sin 37

PR = 22 × 0.60181502315

PR = 13.2399305093

PR = 13.2 units

cos 37 = adjacent / hypotenuse

cos 37 = RQ / 22

RQ = 22 cos 37

RQ = 17.569981221

RQ = 17.6 units
