Which could be the dimensions of a rectangular prism to service area is less than 160 ft.² check all that apply

Area of rectangular prism is given by:

A=2(wl+hl+lw)

where w=width h=height, l=length

checking for given options

1. 8 ft, by 4ft by 3ft

Area = 136 square feet

5. 3 feet by 5 feet by 7 feet

Area =142 square feet

so our first and last option matches the requirement of area less than 160 square feet.

Area of a rectangular prism: 2(wl+hl+hw), given w=width, l=length, and h=height.

Plug the answer choices into this formula to find which one(s) are less than 160 sq. feet.

A. 136 sq. feet

B. 188 sq. feet

C. 202 sq. feet

D. 162 sq. feet

E. 142 sq. feet

So, the only ones that are less than 160 sq. feet are A (8 feet by 4 feet by 3 feet) and E (3 feet by 5 feet by 7 feet).

Your answers are A and E.

I hope this helps :)

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
