576 square inches or 4 square feet
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
How is it a square if its 3ft by 1ft? The perimeter would be 7ft.
1ft-3ft-5ft
generally a 3ft tank is aprox 120L
a yard is 36 inches, right? 3 feet is 36 inches? No 3ft 11in is not less that 1 yd 1ft.
66 square feet
3ft 9in = 45in (1ft = 12in)45in = 114.3cm (1in = 2.54cm)
3ft x 3ft x 1ft = 9 cubic feet of dirt will be needed.
1ft = 12 inches so 3ft = (12 x 3) = 36 inches.
1ft x 3ft= 3ft2
A=L(W) A= 10(3) A= 30ft2
1yd = 3ft 20yd x 3ft/yd = 60ft 60ft + 1ft = 61ft
