Will put braniest to first who answers. erin covered a box with contact paper. the dimensions of the box are shown in the figure below: a rectangular prism is shown. the length of the rectangular prism is labeled as 11 inches, the height is labeled as 9 inches and the width is labeled as 8 inches. the contact paper costs 8¢ per square inch. she will only pay for the contact paper used to cover the box, even if there is waste or extra. how much money did erin spend on the contact paper? $20.72 $41.44 $48.12 $73.14

This problem asks for the surface area of the box, since the contact paper covers the outside (like wrapping paper). The box is 11 x 8 x 9, its length, width, and heighth respectively. And the formula for the surface area of the box is

SA = 2(lw + wh + hl)

SA = 2(11*8 + 8*9 + 9*11)

SA = 2(88 + 72 + 99)

SA = 2(259)

SA = 508 square inches

We are told the contact paper costs eight cents a square inch.

508 square inches x 8 cents / square inch

= $41.44 (the square inches divide out)

Thus, Erin spent $41.444 on contact paper.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
