The question is to find the volume. Thanks in advance (repost because no one answered at all)

  48 cm^3

Step-by-step explanation:

You can count the cubes in the top layer and make the reasonable assumption that the other two layers have the same number:

  (16 cm^3)×3 = 48 cm^3

Alternate solution

The formula for the volume of a rectangular prism is ...

  V = LWH

That is, it is the product of the three dimensions.

  V = (4 cm)(4 cm)(3 cm)

  V = 48 cm^3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
