If each edge of a cube is increased by 50%, then the perce
increase in its surface area is.
(a)
(c)
50%
100%
(b)
(d)
75%
125%​

Answer 1

Answer:

therefore, the answer is (d) 125%.

Step-by-step explanation:

let the length of actual edge be 1.(a)

then the length of 50% increased length would be 1.5 .(A)

TSA of actual cube = 6×1×1=6 sq. units

TSA of larger cube=6×1.5×1.5=6×2.25 sq. units

rate of increase in surface area=[(6×2.25)/(6)×100] - 100

=225-100

=125

hope you are okay with my answer.
