Answer:
72
Step-by-step explanation:
The formula for surface area is SA = 2lw + 2wh + 2lh
W = width
L= length
H = height
A = 2(wl + hl + hw)
2·(6·3+2·3+2·6)
Simplify that down to get the answer 72
Parallel Lines: lines in a plane which do not meet. they do not intersect at any point, so your answer is B.
Answer: AC= 10 cm and CE= 5 cm
Step-by-step explanation:
In the given picture, Δ ADE is a right triangle
∴ By Pythagoras theorem,

Since triangles ABC and ADE are similar and corresponding sides of similar triangles are proportional therefore,

Now, AE=AC+CE
⇒CE=AE-AC
⇒CE=15-10=5 cm
