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
Answer:
130.2 yd²
Step-by-step explanation:
Area of polygon using the length of the side, s, the apothem, a, and the number of sides, n.
A = san/2
A = (6.0 yd)(6.2 yd)(7)/2
A = 130.2 yd²
Answer:
75%
Step-by-step explanation:
<h2><u>Percentage </u></h2>
in a day they are 24 hours. if sadie's dog sleeps for 18 hours , we can create the fraction as :
meaning sadies dog sleeps for 18 hours in a day . we can simplify this by dividing by its common factor 6
=
now we can find the percentage by multiplying it by 100
=
<h3><u>= 75%</u></h3>
if the upper number got power of negative it will go down and the down will go up
So that,
power of 1 can no need to write
