Answer:
2.0833^{3}
Step-by-step explanation:
In order to calculate the cubic yards of concrete that are needed we need to multiply the dimensions of the slab together. Since the dimensions are in different units we need to first convert it all into yards. We know that there are 3 feet in a yard therefore...
15ft = 5 yards
3 inches = 0.0833333 yards
Now that we have all the measurements in yards we simply multiply them together...
5 * 5 * 0.0833333 = [tex]2.0833^{3}[/tex]
