When each edge of a cube is increased by 50%, by what percent is the surface area of the cube increased?

125 % increase

Step-by-step explanation:

assume a cube of side 10

then each side surface area = 100 * 6 = 600 units

now consider sides 15 (+50%)

each side = 225    225 * 6 = 1350

(1350 - 600)/600  = 1.25 =  125 % increase

i think it might be a but you might want a second opinion

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
