Answer:
86.64cm^2 (cm squared)
Explanation:
So! This is a cube, a 6-sided shape. All the side lengths will be equal, which makes it really easy to calculate the surface area.
Since you calculate surface area by length x width, you do that once and then multiply it by six to find the total surface area.
So it'd be 3.8cm x 3.8cm = 14.44cm
and then 14.44 cm x 6 = 86.64cm^2, or cm squared.
