Answer:
V = 1428 in
Step-by-step explanation:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
so:
16*8.5*10.5
Answer:
786.5
Step-by-step explanation:
16 x 10.5 = 168 x 2 = 336. 16 x 8.5 = 136 x 2 = 272. 8.5 x 10.5 = 89.25 x 2 = 178.5. 336 + 272 + 178.5 = 786.5
