Answer:
A = 3.706 square meters
Explanation:
the length of a cube has equal side.
therefore, the volume of a cube is given by S³
V = S³ = 7.14
where S is the length of a side
the surface area of a cube is = 6S²
where the area a aside is calculated, then it is multiply by 6.
if S³ = 7.14
S = ∛(7.14) = 1.925 m
What is the cross-sectional area that is parallel to one of its faces?
this is saying we should calculate for the cross-sectional area of one face. All faces in a cube is equal and parallel to each other.
the crossectional area of one side of a cube is = S² = 1.925² = 3.706 square meters
A = 3.706 square meters
