If the volume of a cube is 64 cm cube then find its total surface area
2 answers:
Answer:
96 cm²
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the side length )
Here V = 64 , thus
s³ = 64 ( take the cube root of both sides )
s = = 4
A cube has 6 congruent square faces.
The area of 1 face = s² = 4² = 16 cm², thus
area of 6 faces = 6 × 16 = 96 cm² ← surface area
