Question 203488
Volume (V) of a rectangular solid (prism) is either l*w*h or B*h where
l = length
w = width
h = height
B = area of the base<br>
We can use either formula. The only tricky part of this problem is in interpreting "a base that is 1.2 meters square". This does <b>not</b> mean that the base has an <i>area</i> that is 1.2 square meters. It means that the base is a square with sides of 1.2 meters! (IOW: "meters square" is not the same as "square meters".)<br>
Now we can solve the problem:
V = l*w*h
l = 1.2
w = 1.2
h = 2
V = (1.2)*(1.2)*(2) = 2.88 cu. meters<br>
If we want to use the second formula instead we need to find the area of the base (B). Since the base is a square the area is:
B = (1.2)*(1.2) = 1.44
Then
V = B*h
V = (1.44)*(2) = 2.88 cu. meters
