Answer: 11.5m^3
Explanation:
The volume of a rectangular prism (R):
length x width x height
Replacing with the values given and solving for v(Volume)
V(R) = 4x 2 x 1
V(R) = 8m3
Volume of a triangular prism (T): base area X
height
Base area = 1/2 x base × height (of the triangular base)
A = 1/2 x1x 3.5 = 1.75m2
Back with the volume formula:
V (T)= Ax h= 1.75 x 2 = 3.5m3
Adding both volumes:
8 +3.5 = 11.5 m3
Hope this explains it
Answer:
1 7/10 miles
Step-by-step explanation:
Halfway around the park is ...
(3/5 mi) +(1/4 mi) = 12/20 mi +5/20 mi = 17/20 mi
Then all the way around the park is ...
2×17/20 mi = 17/10 mi = 1.7 miles
It is 1.7 miles around the park.
D=r×t, plug in the numbers,
150=30×t.
then divide each side by 30.
150÷30=5
5=t
therefore, it will take him 5 hours.
