Answer:
27 ft^3
Step-by-step explanation:
The total surface area of the cube is 54 ft^2.
A cube has 6 congruent square sides.
54 ft^2/5 = 9 ft^2
Each square side has area 9 ft^2.
The area of a square is the square of the side, so the side of a square is the square root of the area.
side = sqrt(9 ft)^2 = 3 ft
The volume of a cube is the cube of the side.
volume = (3 ft)^3
volume = 27 ft^3
- 4(20+22)
- 4(40+2)
This expression are equivalent to 4(42)
Answer:
If simplifed, it'll be -v
Step-by-step explanation:
In left one)
the 3 angles are equal so the sides are equal then we can say

then x is 30÷11
the right one) is exactly similar
