SAT Subject Test Mathematics Level 1

(Marvins-Underground-K-12) #1
Volume  of  Cylinder    =   πr^2 h  =   π(3^2 )(2)=18π ≈56.55

The answer is (E). Applying the formula was the easy part. Visualizing the
cylinder and figuring out what’s r and what’s h was the challenging part. A
typical Mathematics subject test will include one or two questions that entail
visualizing. Here's another one in Example 5.


Example 5

Notice that each of the dimensions 7, 5, and 4 of each rectangular block is a
factor of one of the inside dimensions 16, 15, and 14 of the rectangular carton.
Specifically, 7 is a factor of 14 (14 = 2 × 7), 5 is a factor of 15 (15 = 3 × 5), and 4 is
a factor of 16 (16 = 4 × 4). So you can place the blocks in the carton by placing
the dimension 7 of the blocks along the dimension 14 of the carton, the


The maximum possible    number  of  identical   rectangular blocks  are
placed inside a rectangular carton. The rectangular blocks each have a
length of 7, a width of 5, and a height of 4, and the rectangular carton
has inside dimensions that are a length of 16, a width of 15, and a
height of 14. What is the total surface area of the rectangular blocks
that are inside the rectangular carton?
