Answer:
perimeter=sum of all sides=a+b+c+d=10+8+5+3=26cm
It's sine of 90-18, that is, sine of 72 degrees.
Answer:
x = 75
Step-by-step explanation:
Assuming the angles are equal ( bisected means divided in half)
2x-5 = 145
Add 5 to each side
2x-5+5 = 145+5
2x = 150
Divide by 2
2x/150/2
x = 75
The edge length of the cube ice is 40 inches.
The surface area of the cube ice is 9600 inches²
<h3>
Volume of the cube Ice</h3>
The volume of a cube can be represented as follows:
where
L = length of cube
Therefore,
volume = 64,000
64000 = L³
L= ∛64,000
L = 40 inches
<h3>Surface area of the cube Ice</h3>
The surface are of a cube can be describe as follows:
Surface area = 6 × (40)²
Surface area = 6 × 1600
Surface area = 9600 inches²
