Answer 1

Ok, um so you multiply 26 and 21 to get 546 and then multiply 546 by 15 to get 8,190. So 8,190 ft to the third power would be your final answer

Answer 2

V = LWH
Voloume = Length × Width × Height 

1. V = 21 × 26 × 15 
    V = 546 × 15 
    V = 8,190
     The volume is 8,190 

2. V = 5 × 7 × 2 
    V = 70
    The volume of the sandbox is 70
