Answer:
120 cm^3
Step-by-step explanation:
volume = lwh
I = 4 centimeters
w = 5 centimeters
h = 6 centimeters
volume = (4 cm)(5 cm)(6 cm)
volume = 120 cm^3
Let the speed of the current equal c
and the speed of the boat in still water equal b.
b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c
The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph
