To make things easier, this solid can be divided in 3 parts:
- the first one is 2in long, 5in wide and 8in tall
- the second one is 2in long, 8in wide and 3in tall
- the third one is just like the first one, so 2in long, 5in wide and 8in tall
In order to find the volume of the solids, we need to multiply their dimensions:
1st: 2.5.8 = 80
2nd: 2.8.3 = 48
3rd: 2.5.8 = 80
The volume of the big solid is equal to (80 + 48 + 80)
V = 208
Answer:
n = 2
Step-by-step explanation:
Given
(n - 4) - 3 = 3 - (2n + 3)
Multiply through by 2 to clear the fraction
n - 4 - 6 = 6 - 2(2n + 3) ← distribute
n - 10 = 6 - 4n - 6 ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2
