Step-by-step explanation:
The volume of the prism that its faces is made from 6 identical squares is 48 cm³.
<h3 /><h3>Volume of a square prism</h3>
A square prism is a 3-dimensional cuboid where the base and top are equal squares.
where
a = side length
h = height
Therefore,
a = 2 cm
h = 12 cm
Therefore,
v = a²h
v = 2² × 12
v = 4 × 12
v = 48 cm³

Answer:
C. Yes, we can prove the triangles congruent by SAS.
Step-by-step explanation:
In ∆ABC and ∆DEF,
BC = EF = 6 cm
angle A = angle D = 22°
AC = DF = 14 cm
Hence, the triangles are congruent.
