What is the surface area of the figure?
a.
270 cm2

b.
135 cm2

c.
160 cm2

d.
320 cm2

We can split it up into a net
actually, here is a hack

notice that indented side?
we can take the plane and push it so it makes 4 sides, neat

ok, so we now just have 4 normal sides and 2 L shapes

L shape can be cut into 2 rectangles
5 by 5 and 5 by 10 so total of 75 is the L
2 L's so
2*75=150

the sides
4 of them
they all are 10 by 3
10*3*4=120

toatl is 150+120=270

answer is A

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
