Answer:
12 m³
Step-by-step explanation:
The bottom platform has dimensions 2m × 4m × 3m, so a volume of ...
V = LWH
V = (2 m)(4 m)(3 m) = 24 m³
The top platform has dimensions 2m × 3m × 2m, so a volume of ...
V = (2 m)(3 m)(2 m) = 12 m³
The bottom platform has a larger volume by ...
24 m³ -12 m³ = 12 m³
The bottom prism has a 12 m³ larger volume.
Answer:
(an -a1)/d +1 = n
Step-by-step explanation:
Undo what is done to n, in reverse order. When evaluating this expression, you ...
- subtract 1 from n
- multiply the difference by d
- add a1
When you undo these, you get ...
... an -a1 = d(n-1) . . . . . . subtract a1
... (an -a1)/d = n - 1 . . . . divide by d
... (an -a1)/d +1 = n . . . . add 1
