Data:
LB=5ft 6in
WW= 4ft 5in
ST=6ft
VP=6ft 8in
JL= 5ft 6in
UD=6ft=7in
Furniture height:
Top shelf=92in
Table=25in
Stael=13in
Step lader=39in
Stack of books=43in
As 1ft is equal to 12in we can convert measurements of the persons in inches with the next formula:
LB=66 in
WW= 48in
ST=72in
VP=80in
JL= 66in
UD=79in
To reach the top shelf (92in):
Everybody will need:
LB needs 92-66 = 26in
WW needs 92-48=44in
STneeds 92-72= 20in
VP needs 92-80= 12in
JLneeds 92-66= 26in
UD needs 92-79=13in
Then:
- LB can take the step lader or the stack of books to reach the top shelf
(LB+Step Lader= 66+39=105) or (LB+ stack of books =66+43=109in)
- WW can't reach the top shelf using just one piece of furniture
-ST can use the table, the step lader or the stack of books
(ST+table=72+13=85)or (ST+Step Lader= 72+39=111) or (ST+ stack of books =72+43=115in)
-VP can use the stael, or the table or the step lader or the stack of books to reach the top shelf.
-JL can use the step lader or the stack of books to reach the top shelf.
-UD can use the stael, or the table or the step lader or the stack of books to reach the top shelf. If UD uses the stael reach the top shelf in a exact measure (UD+stael=79+13=92)
