Answer:
9 m³
Step-by-step explanation:
This block has the shape of a rectangular prism.
The volume of such a prism is A = (length)(width)(height).
Here, the volume is V = (3 m)(1.5 m)(2 m) = 9 m³
The answer is 16, half of 32 1/8 x 1/2 = 2/16 divided by 2/2 = 1/8 but since you don't need to simplify only use the denominator of 2/16 or only need to multiply 8 and 2.

Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour
