50 points if u help with all!
hurry plz do in 5 mins where I live

Number 4 is 9 2/8 because if u add the 4 and 5 that is 9 and if u add 1 and 1 that is 2 and multiply 2 and 4 that is 8.

1. V= 9ft x 8ft x 7ft = 504ft cubed

2. V= 13in x 4in x 5in = 260in cubed

V= 3in x 4in x 8in = 96in cubed  260 + 96 = 356in cubed

3. V= 1 1/2ft x 3/4ft x 2ft = 2 1/4ft cubed

4. A= 5 1/4ft x 4 1/2ft = 23 5/8ft squared

5. Number of cubes= 18

V= 18
