Find the surface area of all the sides with a width and length first can you do that?
well heres a hint: two sides have an area of width * length
Very good! now since theres TWO sides so multiply by 2 to get:102.96
Ok so now we have 4 more faces. 2 of them are width*height and length*height
width*Height would be 6.2*h=6.2h
length*height would be 8.3*h=8.3h
now you solve for h (height) by using this equation: 102.92+6.2h+8.3h=458.17
102.92+14.5h=458.17 14.5h=458.17-102.92 14.5h=355.25 h=24.5 So, height is 24.5
wit are your options??
hmmm gimmee a sec
do you know what surface area is?
first, draw a rectangular prism and see if you can better visualize the problem
draw it here
OK THIS TOOK ME FOREVER BUT HERE IT IS
SA = Surface Area = 458.17 in² L = Length = 8.3 in W = Width = 6.2 in H = Height = What we're solving for. The formula for the surface area of a rectangular prism is SA = 2*(LW + LH + WH) Substituting values: 458.17 = 2*(8.3*6.2 + 8.3H + 6.2H) 229.085 = 51.46 + 14.5H 14.5H = 229.085 - 51.46 H = 117.625/14.5 H = 12.25 inches. That's about it! =)
looks at meh new method and see if ya understand :P
is that a rectangular prism ?
that does not look like a prism to me
the answer is 12.25inches
HEY NIN UR A HELPER NOW!! :D
it's a rectangular prism drawn out...
no! that is not a prism
obviously not but it's flat out and labeled
:c my hard work is ignore *clicks on another question*
my online course taught me to draw and label the surfaces of the figure like that
SA = Surface Area = 458.17 in² L = Length = 8.3 in W = Width = 6.2 in H = Height = What we're solving for. The formula for the surface area of a rectangular prism is SA = 2*(LW + LH + WH) Substituting values: 458.17 = 2*(8.3*6.2 + 8.3H + 6.2H) 229.085 = 51.46 + 14.5H 14.5H = 229.085 - 51.46 H = 117.625/14.5 H = 12.25 inches. Notice me senpai
when asked to draw a rectangular prism, try to draw it the way it should look first and then lay it out broken down AFTER you properly labeled them
well i did both on my paper but it made more sense to draw out the flat out version online instead of wasting time and drawing out both but it's alright i get it
ok so what now
