  Read the following SAT test question and then click on a button to select your answer.

  What is the maximum number of nonoverlapping squares with sides of length3that will fit inside of a square with sides of length6?

  (A) Two

  (B) Three

  (C) Four

  (D) Six

  (E) Nine

  The correct answer is C

  Explanation

  Choice (C) is correct. A square with sides of length3has area9, and a square with sides of length6has area36. Thus at most36 divided by 9 equals 4squares of side length3can fit inside a square of side length6without overlapping. And in fact, it is possible to fit the four squares of side length3inside a square of side length6with no overlap; if the four squares with sides of length3are arranged in two rows with two squares in each row, they will fit inside of the square with sides of length6without overlapping. Therefore, the maximum number of nonoverlapping squares with sides of length3that will fit inside of a square with sides of length6is four.

  下面为大家提供一些和这些SAT官方每日一题相似的题目,供大家练习:

  A right circular cylinder has height6and volume54 times pi. What is the circumference of its base?

  (A)2 times pi 

  (B)3 times pi 

  (C)6 times pi 

  (D)9 times pi 

  (E)18 times pi 

  The correct answer is C

  Explanation

  The volume of a cylinder with radiusrand heighthis equal topi times (r^2) times h. Therefore,pi times (r^2) times (6) = 54 times piandr^2 = 9, so the radius of the cylinder is3. The circumference of a circle with radiusris equal to2 times pi times r; therefore, the circumference of the base is equal to6 times pi.
