So you need to find the volume for the rectangular prism (1) and the rectangular prism in the center of it (2)
The formula for a rectangular prism is:
V = lwh [Volume = length x width x height]
1.
l = 15
w = 6
h = 6
V = lwh Plug in the numbers
V = (15)(6)(6) = 540
2.
l = 15
w = 4
h = 4
V = lwh
V = (15)(4)(4) = 240
Next you subtract the volumes by each other because the rectangular prism in the center(2) is the hole/empty part of the rectangular prism(1)
V = V(1) - V(2)
V = 540 - 240
V = 300
They got the 1.2 minutes by taking the total number of minutes (6) and dividing them by the number of laps run (5). So 6 divided by 5 gives you the 1.2.
Answer:
first get a common denominator by multiplying 7 and 4 to get 28
28 is our common denominator here.
Step-by-step explanation:
We want to add the fractions 2/7 and 1/4
(2/7) * (4/4) and (1/4) * (7/7)
(2/7) * (4/4) + (1/4) * (7/7) = 8/28 + 7/28 = 15/28
