Answer:
here
Step-by-step explanation:
Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15
the answer is c
384 in³
the volume (V) of a cuboid = length × width × height
V = 12 × 4 × 8 = 384 in³ ← fourth on list
I believe it’ll be 4/10 = 12/20
