A block occupies 0.2587 ft^3. What is its volume in mm^3

Answer 1

1 inch = exactly 2.54 cm by definition

= 25.4 mm

1 cm = 10 mm

1 in^3 = 25.4^3 = 16,387.064 cm^3

1 ft^3 = 12x12x12 x 16,387.064.064 cm^3= 28,316,846.59 cm^3

1 ft^3 = 1000 x 23,316,846,590 mm^3

1 cm^3 = 1000 mm^3

.2587 ft^3 = .258(23,316,846,590) = 7,325,568.213

12 inches = 12(2.54) = 30.48 cm = 304.8 mm = 1 foot

304.8^3 = 28,316,846.59

times .2587 = 7,325,568.213 mm^3

.2587 ft^3 = almost 7 1/3 million mm^3
