If a cube with the length of the side of 4 cm is cut into smaller cubes with the length of the side of 1 cm, then what is the percentage increase in the surface area of the resulting cubes?

300 %

Step-by-step explanation:

Length of the larger cube =4 cm

So volume

Length of the smaller cube = 1 cm

Volume of the smaller cube

So total number of smaller cube

Surface area of the larger cube

Surface area of the 64 smaller cube

So percentage increase in surface area %

answer: i oofed

step-by-step explanation:

oofed=wow

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
