Step-by-step explanation:
it is a box or prism.
the volume is simply
length × width × height
in our case
8m × 6m × 5m = 240 m³
doubled dimensions means
16m × 12m × 10m = 1920 m³
the difference is
1920 - 240 = 1680 m³
we could have gotten the new volume also based on the original volume :
2×8m × 2×6m × 2×5m = 8m×6m×5m × 2×2×2 =
= the original volume (240 m³) × 8 = 1920 m³
As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.
Where 
represents base (hypotenuse) and 
as height of the triangle.
We know that:
Using this data we fill the formula.
Hope this helps.
