The answer has a meaning only in 4-dimensional space. 10 sq ft * 7 sq ft = 70 quartic feet.
30 x 10 = 300 sq. ft. 10*30=300 therefore it is 300 sq. ft.
10 * 10 = 100 square feet!
Top = 5 x 3 = 15 sq ft Bottom = 5 x 3 = 15 sq ft 2 sides = 5 x 7 = 35 sq ft each other 2 sides = 3 x 7 = 21 sq ft each Total cardboard = 142 square feet Surface area = 142 sq ft inside, and 142 sq ft outside.
16 ft x 7 ft = 16 x 7 square ft = 112 sq ft
9 ft 6 in x 11 ft 7 in = 9.5 ft * 11.583... ft = 110.04166.. sq ft = 110.04166.. /9 sq yards = 12.227 sq yards, approx.
Impossible because 'sq'ft' is a measure of AREA. 'Inches is a measure of 'LENGTH'. However, 'Sq.Ft'' can be converted to 'sq'ins' . by multiplying by '144' There are 144 sq. ins = 1 sq.ft. So 10 sq.ft. = 1440 sq. ins.
150 sq. ft.
10 sq ft * 15 sq ft = 150 ft4, a hyper-volume in four-dimensional space.
7 ft x 7 ft = 49 square feet
10 ft x 29 ft = 290 sq ft
30 x 10 = 300 sq. ft. 10*30=300 therefore it is 300 sq. ft.
12 inches = 1 foot Each paver is 1 sq. ft. 10 ft. x 10 ft. = 100 sq. ft. 100 sq. ft. divided by 1 sq. ft. = 100 pavers
100 sq ft
15 x 10 = 150 (sq ft).
10 * 10 = 100 square feet!
Top = 5 x 3 = 15 sq ft Bottom = 5 x 3 = 15 sq ft 2 sides = 5 x 7 = 35 sq ft each other 2 sides = 3 x 7 = 21 sq ft each Total cardboard = 142 square feet Surface area = 142 sq ft inside, and 142 sq ft outside.
A "square" of shingles is 10 ft x 10 ft totaling 100 sq ft. So, the amount you will need would be 60ft x 30ft = 1800 sq ft/100 sq ft = 18 sq Good luck.
