Part 2) <span>What is the surface area of this cube?
we know that
surface area of a cube=6*b</span>²
where b is the length side of a cube
in this problem
b=15 mm
so
surface area of a cube=6*15²----> 1350 mm²
the answer Part 2) is 1350 mm²
Part 3) What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=11 cm
so
surface area of a cube=6*11²----> 726 cm²
the answer Part 3) is 726 cm²
part 4) <span>What is the surface area of the rectangular prism represented by the net?
surface area=2*16*6+2*16*8+2*6*8----> 544 cm</span>²
the answer Part 4) is 544 cm²
Part 5) <span>What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in</span>²
the answer part 5) is 105 in²
Answer:
0.3643
Step-by-step explanation:
3.643×10^-1 = 3.643×(1/10) = 3.643×0.1 = 0.3643
we have
-----> equation 
-----> equation 
Resolve the system
we know that
the solution of the system is the intersection of both graphs
Multiply by 
equation
Adds equation and equation
find the value of y
the solution is the point 
therefore
the answer is
The solution is the graph in the attached figure
