Suppose you have a rectangular shipping box that measures 30 cm × 15 cm × 20 cm. what is the longest length of a 1 cm diameter wooden dowel that could fit inside the box? (round to the nearest whole centimeter) plz hurry i need it before 12: 40pm 1-22-18

39 cm

SOLUTION

Given,

Length, L = 30 cm

Breadth, B = 15 cm

Height, H = 20 cm.

The longest length of a 1 cm diameter wooden dowel that could fit inside the box = The diagonal, D of the box (from the lower front left corner to the upper back right corner)

Diagonal, D = ?

D^2 = L^2 + B^2 + C^2

D^2 = 30^2 + 15^2 + 20^2

D^2 = 900 + 225 + 400

D^2 = 1525

D = 39 cm (to the nearest whole centimeter)

Therefore, the longest length of a 1 cm diameter wooden dowel that could fit inside the box is 39 cm (to the nearest whole centimeter).

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
