Answer:
192 cubes.
Step-by-step explanation:
The volume of each cube = (side)³ = (1/4)³ = 1/64 units ³
Next is to find how many cubes are needed to fill the prism.
The number of cubes that will fill the prism :
Vol. of prism / Vol. of cube = 3 /
=192 cubes.
Therefore, it takes 192 cubes to fill the prism.
Question:

Round to 2 decimal places feet.
Answer:
Step-by-step explanation:
The question is illustrated using the attachment as a sketch.
We have that
Required
Determine how high the ladder is to the building
Represent the length of the ladder with L and how high the ladder is on the building with H.
The relationship between L, H and is"
Substitute values for L and
Make H the subject
<em>Hence, the height to which the ladder reaches is approximately 31.88ft</em>
