To answer the problem above, I assumed the object to be a rectangular prisms. To solve for the volume of such figures, multiply all three dimensions. This is mathematically expressed as,
V = H x D x L
V = (1.5 ft) x (4 ft) x (2 ft) = 12 ft^3
The volume of the object is 12 ft^3. Thus, the answer is letter A.
9, the tens digit, is six more than 3, the ones digit. 1, the hundreds digit, is 8 less than the tens digit, 9. It can't be any other number combination than this.
