Given:
Rectangular prism
Length = 2.5x
Width = x
Height = 6 feet
Volume = 2,940 feet³
Volume = Length * Width * Height
2,940 ft³ = (2.5x) * x * 6ft
2,940 ft³ ÷ 6 ft = 2.5x²
490 ft² = 2.5 x²
490 ft² ÷ 2.5 = x²
196 ft² = x²
√196 ft² = √x²
14 ft = x
Width = x = 14 feet
Length = 2.5x = 2.5 * 14 ft = 35 feet
We’ll first find how much she has left as her savings
$490-$396.90= $93.70
Now we’ll go for cross multiplication
100% $490
? $93.70
? = 100 x 93.7/490
? = 19.1 %
So the answer is 19.1% which rounded to the nearest whole number is 19%. The answer is the first option.

Step-by-step explanation:
Answer:
The measure of each side of the cube is
<h2>15 inches</h2>
Step-by-step explanation:
Since it's a cube all it's sides are equal
To find the length of each side we use the formula
Volume of a cube = l³
where l is the measure of one side
From the question
Volume = 3375 cubic inches
Substitute this value into the formula and solve for l
That's
<h3>

</h3>
Find the cube root of both sides
That's
<h3>
![\sqrt[3]{ {l}^{3} } = \sqrt[3]{3375}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%7Bl%7D%5E%7B3%7D%20%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7B3375%7D%20)
</h3>
We have the final answer as
<h3>l = 15 inches</h3>
