The volume or cubic contents of any body is found by solid or cubic measure, a practical knowledge of which is most useful to commercial gardeners. Before proceeding to give examples, the following tables may be noted: -

1 cub. ft. = 1728 cub. in.

27 cub. ft. = 1 cub. yd. = 46,656 cub. in.

1 cub. ft. of water = 1000 oz. avoir, (really 997137 oz.) = 625 lb.

1 pt. of pure water weighs 1 1/4 lb.

1 gal. of water = 10 lb. = 277 cub. in.

 oz. cub. in. gill. 5 = 8.664 = 1 pt. 20 = 34.659 = 4 = 1 qt. 40 = 69.318 = 8 = 2 = 1 gal. 160 = 277.274 = 32 = 8 = 4 = 1 pk. 320 = 554.548 = 64 = 16 = 8 = 2 = 1 hush. 1,280 = 2218.192 = 256 = 64 = 32 = 8 = 4 = 1 qr. 10,240 = 17745.536 = 2048 = 512 = 256 = 64 = 32 = 8 = 1

Thus, to find the cubic contents of any square or rectangular solid body, the length, width, and depth are multiplied together. Thus, 1 cub. ft. = 12 in. by 12 in. by 12 in. = 1728 cub. in.

An acre of soil contains 43,560 sq. ft., and at 1 ft. deep is considered to weigh on an average 3,000,000 lb. Therefore 1 cub. ft. of soil weighs on an average 3,000,000/43,560 = 69 lb., nearly. 1 cub. yd. of soil weighs about

1863 lb. = 16.6 cwt. In practice it is reckoned as 1 ton.

In applying these figures to well-known things in gardens and nurseries the following examples may be taken.
