Consider
.
Given:

To find:
The length of BC.
Solution:
We have,

We know that the corresponding parts of congruent triangles are congruent (CPCTC).
(CPCTC)

The length of BC is 5 m. Therefore, the correct option is A.
Answer:
Step-by-step explanation:
V of a cube is s^3
V = 512
s = cube root of (V)
s = cube root of 512 cm^3
s = 8
The area of one face of the cube is s^2
s = 8
Area 1 face = 8^2
Area of 1 face = 64 cm^2
Just multiply w*l*h
1.89m cubed
