Answer:
120 km^3
Step-by-step explanation:
the base is a right triangle
A = (leg1 x leg2)/2 = (6 x 8)/2 = 24 km^2
the volume of a prism is base area x height
V = 24 x 5 = 120 km^3
Answer:
157
Step-by-step explanation:
Given the sequence
7; 17; 37; 77; ___ ; 317
Let the blank space=x
We notice that the difference is always multiplied by 2.
Therefore:
x-77=80
x=80+77
x=157
The number that should be in the blank space of the sequence is 157.
Now, observe the pattern in full:
- 17-7=10
- 37-17=20
- 77-37=40
- 157-77=80
- 317-157=160
