Final answer:
To find the total space the cargo will take up, multiply the number of energy prisms by the space each prism occupies.
Step-by-step explanation:
To calculate the total space that the cargo will take up, we need to multiply the number of energy prisms by the amount of space each prism takes up.
3.5 x 10^5 energy prisms x 2 x 10^2 cubic feet/prism = 7 x 10^7 cubic feet
