Answer:
486 centimeters³
Step-by-step explanation:
Surface area of a cube = 6s²
Where,
s = side length
Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
s = 9 centimeters
Surface area of a cube = 6s²
= 6 × 9²
= 6 × 81
= 486 centimeters³
Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³
2x-6=14 2x=20
a)x=10
-5x5=40 -5x=35
B)x=-7
12x+240=24 12x=-216
C) x=-18
Answer:
Sides other than hypotenuse of an isosceles triangle are equal.
Let the other two sides be x each.
Using pythagoras theorem
x

=50
⇒x

=25
⇒x=5cm
So the other two sides are 5cm each.
