Part 2) 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=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) 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 cm²

the answer Part 4) is 544 cm²

Part 5) What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in²

the answer part 5) is 105 in²

A jar contains five red marbles and three green marbles. A marble is drawn at random and not replaced. A second marble is then d

g100num [7]

Probablility that that first marble is red:
$P_{red} = \frac{red}{total}$
$P_{red} = \frac{5}{5+3}$

Probability that the second marble is green:
$P_{green} = \frac{green}{total(new)}$
$P_{green}= \frac{3}{4+3}$ (because 1 red is now gone)

$P_{total}=P_{red} \times P_{green}$
$P_{total}= \frac{6}{8} \times \frac{3}{7} = \frac{18}{56} = \frac{9}{28} \approx 32.1\%$
