A because ur is the closest and in the range order
Answer:
30 cm
Step-by-step explanation:
Step 1: The surface area of a cube = 6a^2, where "a" is the side of the cube.
Step 2: We are given surface area of a cube = 5400.
Step 3: Now plug in the surface area of the cube = 5400 and simplify.
5400 = 6a^2
a^2 = 5400/6
a^2 = 900
Now take square root on both sides, we get
a = √900
a= 30 cm
Therefore, the side of the cube is 30 cm.
Thank you.
Answer:
dent in what?
