The volume is 300 inches cubed, first I split the figure into three, the volume=L×W×H, for the first box I did 4×4×5=80, the second box I did 6×6×5=180, the third box I did 2×4×5=40, therefore 80+180+40=300
therefore the answer being 300 inches cubed
Answer: we can make 15,504 different math tests
Step-by-step explanation:
Ok, we have a bank with 20 questions (Q1, Q2........ , Q20)
and we want to make a test with 15 of those 20 questions.
As the order of the questions does not matter in the thest ( is the same if the order is Q1, Q2, ...., Q15 than if the order is Q15, Q14, ....., Q1 )
So we only want the number of combinations.
When we have N elements and we want to create groups of K elements, the total number of combinations is:
Here N = 20 and K = 15
So we can make 15,504 different math tests
Answer:
If im not wrong, just multiply wxlxh, for all sides, and you get 1260.
Step-by-step explanation:
4p + 3(p + 4) = 12p + 12
4p + 3p + 12 = 12p + 12
7p + 12 = 12p + 12
5p = 0
p = 0
