Cubic volume=l³
l³= 1728
l= 12 feet
the aquarium is cubic shaped=> all l are equal
one side is a square with l= 12 feet
area= l²= l•l= 12•12= 144 feet²
-1-7x-6(-7-x)=36
-1-7x+42+6x=36
41-7x+6x=36
41-x=36
-x=36-41
-x=-5
Answer: x=5
28 times 1/7 would give you 4
The kite forms a right angled triangle with hypotenuse of 50 ft. The height of the kite above the ground is the opposite of 60° angle.
Using the sine rule,
Sin 60 = Height of the kite above the ground/Hypotenuse
Therefore,
Height of the kite above the ground = Hypotenuse*Sin 60 = 50 *Sin 60 = 43.3 ft
