Answer:

Step-by-step explanation:
A three dimensional configuration with its face shaped of rectangle is called a Cuboid. So, the prism is in the shape of a cuboid.
The volume of a cuboid = Length *Breadth*Height

The volume of the cuboid shaped prism is 
19x-15 = 15x -7
4x = 8
x =2
19(2) -15 = 23
15(2) -7 = 23
Greater 1 km = 1000 m
so it's greater than 999 m
we know that the quatraitic equation
we know that the quadratic equation is aX square + bx + c we put this value A and B and C in equation X square + bx + c
