Answer:
147 
Step-by-step explanation:
7*7*3 = 147
volume of a rectangular prism = length*width*height, in this case, 7*7*3
hope this helps :)
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
13/8 or 1 5/8
3/4 becomes 7/8 when add it is 13/8
