Question

7 cu. yd. 9 cu. ft. 134 cu. in. + 1 cu. yd. 12 cu. ft. 200 cu. in.

Answer 1

7 cu. yd     9 cu. ft.     134 cu. in
1 cu. yd.   12 cu. ft      200 cu. in
--------------------------------------------add
8 cu. yd     21 cu. ft      334 cu. in.

1 cu. yd = 27 cu. ft..... 1 cu. ft. = 1728 cu. in.... 1 cu. yd = 46656 cu in

so 8 cu. yd. = (8 * 27) = 216 cu. ft....+ 21 cu. ft = 237 cu. ft
and 237 cu. ft = (237 * 1728) = 409536 cu. in...+ 334 cu. in =
409870 cu. in <===

or 
409870 cu. in = (409870 / 1728) = 237 cu. ft , 334 cu. in <==
or
(237 / 27) = 8 cubic yd , 21 cu. ft, 334 cu. in <==
or
409870 cu. in = (409870 / 46656) = 8 cu. yd., 36622 cu. in <==

not sure which one u want to use...
