If 1/3 of this class was absent and we have 23 students, how many would not be in class?
7.6 students (or 7 you can't have 0.6 of a person)

Why in our lab did we have to subtract the area of the land from the area of the container to take the area of the water?
The land was not covered in water and was therefore taking away an area of space away from the water.
Find the volume of a shape with the dimensions of:
l= 3.2cm w= 4.6cm h= 5.1cm
75.072cm^3
Explain why units I want to cancel out go in opposite sides of a fraction
Because anything divided by itself (including units) just equals 1.
If 1/6 of the class was absent and there are 23 students total, how many would be present in class?
19.2 (or 19 because you can't have half a student)
The sea level rise of 2.3m corresponds to 23,000km^3 of ice. How much would the sea rise if only 12,500km^3 melted?
(2.3m=23,000km^3)
1.25m
Explain why sea ice does not contribute to sea level rise when it melts.
The sea ice is already displacing the water when it is frozen.
Find the new water height if the volume of ice which melted into it was 12,400km^3 and the water's area was 34,800km^2
0.356km
