10 boxes measuring 30" x 21" x 17" = cbf round to nearest whole number

61.979 cbf

Step-by-step explanation:

Data provided in the question;

Dimension of the box = 30" × 21" × 17"

Number of boxes = 10

the volume of box in in³= 30" × 21" × 17" = 10710 in³

Total volume of 10 boxes = 10710 × 10 = 107100 in³

Now,

cbf = cubic feet i.e the unit of volume

also,

1 in³ =

thus,

107100 in³ =

or

= 61.979 ft³ or 61.979 cbf

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

(x) - (y) = (1 + 4i)
