This cube has 6 faces, and all side lengths are equal.
The volume of a cube with sides of length L is given by L^3.
The problem says that the volume is 7^3, which means that each side is 7
The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:
6*7^2 = 6*49 = 294 cm^2
Answer:
This is proved by ASA congruent rule.
Step-by-step explanation:
Given KLMN is a parallelogram, and that the bisectors of ∠K and ∠L meet at A. we have to prove that A is equidistant from LM and KN i.e we have to prove that AP=AQ
we know that the diagonals of parallelogram bisect each other therefore the the bisectors of ∠K and ∠L must be the diagonals.
In ΔAPN and ΔAQL
∠PNA=∠ALQ (∵alternate angles)
AN=AL (∵diagonals of parallelogram bisect each other)
∠PAN=∠LAQ (∵vertically opposite angles)
∴ By ASA rule ΔAPN ≅ ΔAQL
Hence, by CPCT i.e Corresponding parts of congruent triangles PA=AQ
Hence, A is equidistant from LM and KN.
1/3 ÷1/4 = 1/3 × 1/4 = 1/12
