Answer :

To determine the volume of a rectangular space, you use the formula for the volume of a rectangular prism:

[tex]\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \][/tex]

Given the dimensions:
- Length = 10 feet
- Width = 30 feet
- Height = 10 feet

Substitute the given values into the formula:

[tex]\[ \text{Volume} = 10 \, \text{feet} \times 30 \, \text{feet} \times 10 \, \text{feet} \][/tex]

Simplify the multiplication step-by-step:

1. Multiply the length and width:
[tex]\[ 10 \times 30 = 300 \][/tex]

2. Multiply the result by the height:
[tex]\[ 300 \times 10 = 3000 \][/tex]

Therefore, the volume of the rectangular space is [tex]\( 3000 \)[/tex] cubic feet.

So, the correct answer is:
3000 ft³
