Answer:
52 cm²
Step-by-step explanation:
There are 3 distinct faces:
one with sides 2 and 3
one with sides 2 and 4
one with sides 3 and 4
There are two of each distinct face (they are accros each other)
so we find their areas (we times by two as there are two of each face)
2×3×2=12
2×4×2=16
3×4×2=24
Finally we add the values:
12+16+24=52 cm²
