Answer:
Since GI bisects that means the angle is cut into 2 equal angles or
DGI = IGH
So
x - 3 = 2x - 13
Solve for x
13 - 3 = 2x - x
10 = x
x = 10
Answer:
12
Step-by-step explanation:
144 divided by 12 is 12
The new cube will have 7 surfaces: 4 equal square sides, 2 square surface with a hole, and one hole surface.
Area (A1) of 4 square surfaces = 4*L*W = 4*4*4 = 64 cm^2
Area (A2) of the two surfaces wit a hole = 2(L*W - 2πd^2/4) = 2(4*4-π*2^2/4) = 25.72 cm^2
Area (A3) of the hole = πD*W = π*2*4 = 25.13 cm^2
Total surface area, A = A1+A2+A3 = 64+25.72+25.13 = 114.85 cm^2
