Answer:
300 squared unit of measurement
Step-by-step explanation:
12*5*5
12*5 = 60
60*5 = 300
I am assuming this is a rectangular prism
[see below]
m∠ JHI + m∠GHJ = 180 { linear pair}
m∠JHI + 90 = 180
m∠JHI = 180 -90 = 90
In ΔGHJ and ΔJHI,
GJ = IJ { given}
JH = JH {common}
m∠ JHI = m∠GHJ { above proved}
ΔGHJ ≅ ΔJHI { Angle Side Side congruence}
