I made a fort by connecting two boxes. The first box is 5 meters long, 9 meters wide, and 9 meters high. The second box is 3 meters long, 8 meters wide, and 2 meters high. How many cubic meters of space does my fort have?

453 cubic meters.

Step-by-step explanation:

volume of a box with dimensions of length l, breadth b and height h = l*b*h so, volume of the first box here is 5*9*9=405 cubic meters volume of the second box here is 3*8*2=48 cubic meters total volume of the fort = 405+48 = 453 cubic meters space of a fort or any other thing is total volume contained in it. so, number of cubic meters of space the fort has is 405 + 48

=453
