The surface area is 216 cm sq.
Square base formula: length * width
One square base is 70 cm sq (7*10), another is 56 cm sq (7*8), and the final base is 42 cm sq (7*6).
The height of both triangular faces is 4.8 cm
The two triangular faces are 24 cm sq each, 48 cm sq when added together.
Add all 5 numbers up to get 216.
There are 2 lines, so this is a system of inequalities.
Find the equation of both lines:
The longer line using points (0,6) and (3,3)
Equation is y = -X+6, the inequality becomes y ≥-x+6
The equation for the shorter line:
Using points (5,1) and (6,2)
Equation is y=x-4, the inequality becomes y≤x-4
The system of inequalities is:
y ≥-x+6
y≤x-4
10/21 because there are no common numbers between those 2 numbers
A=5.00
B=7.07
