Question

Karan has 3 boxes of different size the first box is 10 cm then the third box and second box is 5 cm is shorter than the third box if the total length of 3 boxes is 80 cm find the length of each box ​

Answer 1

Step-by-step explanation:

first box(x) = 10cm+z

second box(y) = z-5

third box= z

x+y+z= 80cm

z+ 10+ z-5+z = 80

3z+5= 80

3z= 80-5

3z= 75

z= 75/3= 25

therefore, first box= 10cm +z= 35cm

second box= z-5= 20cm

third box= 25cm
