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
(13x² + 5x) + 8x²
= (13 + 8)x² + 5x
= 21x² + 5x
Divide the number of defective by the number checked:
26/190 = 0.1368
Multiply that by 1000:
0.1368 x 1000 = 136.8
Round up to 137
Out of 1000 cd’s 137 would be defective
1 mile is 6 times
5/6 of a mile... x times
<span>x= 5/6 x 6 = 30/6= 5 times</span>
