Question

Using the correct number of significant figures, calculate the perimeter and volume of a small, rectangular mirror that is 4.040 in long, 1.707 in wide, and 0.078 in thick. Make sure to calculate the the perimeter of the front of the mirror, and not the side. Dimensions are given in inches but the final answer should be in centimeter

Answer 1

Perimeter = 2(4.04) + 2(1.707)

Volume = 4.04 * 1.707 * .078

Convert to cm.

1 inch = 2.54 cm

Answer 2

volume in inches: 4.04 * 1.707 * 0.078 = 0.53790984 in.
perimiter in inches: 2 (4.04) + 2 (1.707) = 11.494 in.
vol. in cm. : 1.3662909936
per. in cm. : 29.19476
