Answer :
To determine the volume of a cube with an edge length of 1.5 feet in cubic meters, we need to follow these steps:
Find the volume of the cube in cubic feet.
- The formula for the volume of a cube is [tex]V = a^3[/tex], where [tex]a[/tex] is the edge length of the cube.
- Here, [tex]a = 1.5[/tex] feet.
- So, [tex]V = (1.5)^3 = 3.375[/tex] cubic feet.
Convert the volume from cubic feet to cubic meters.
- We know that [tex]1[/tex] meter [tex]= 3.281[/tex] feet.
- Therefore, to convert feet to meters, we divide by [tex]3.281[/tex].
- Thus, to convert cubic feet to cubic meters, we use the conversion factor [tex](\frac{1}{3.281})^3.[/tex]
Calculate the conversion.
- [tex]3.375 \text{ ft}^3 \times \left(\frac{1}{3.281}\right)^3 \approx 0.0959 \text{ m}^3.[/tex]
Therefore, the volume of the cube with an edge of 1.5 feet is approximately [tex]0.0959 \text{ m}^3.[/tex] This corresponds to option E) 9.6 \times 10^{-2} \text{ m}^3.
