3.) Find the surface area of this right rectangular prism to the nearest tenth of a square centimetre
Surface Area= 2(18.5)(13.5)+2(18.5)(5)+2(13.5)(5)
= 499.5+185+13 = 697.50 cm
5.) Calculate the surface area of this ramp in the shape of a right triangular prism.
Surface Area= 2(1.4)(2.3)+(2.3+2.7+0.7)
Surface Area= 6.44+5.7 = 12.14 m
Cylinder Volume and Volume Problems
r= d/2
r= 8/2
r= 4 m2
v= π x r x r x h
v= 3.14 x 4 x 4 x 10
v= 501.4 m3
v= 2 x 2 x 15
v= 60 m2
The volume of the rectangular prism is 60m.
r= d/2
r= 1/2
r= 0.5 m2
v= π x r x r x h
v= 3.14 x .5 x .5 x 15
v= 11.775 m3
The volume of the cylinder is 11.775 m360-11.775
= 48.225
The volume of concrete required for one culvert piece is 48.225 m3.
Nice concise post, Shane! Next time add a video or link to enhance your presentation!
ReplyDeleteNot bad, Shane. I agree with Duyen as well. A link to a site and a video would make this post just as helpful. Remember not to use colours unless necessary like when highlighting something important.
ReplyDeleteGood job Shane! I noticed that it's not complete but great job with the pictures. Maybe next time, add a link or something to improve your post.
ReplyDeleteGreat job explaining how you got your answer shane. Next time you should add a video and link to make your post deeper to your point.
ReplyDeleteGreat job Shane. Great use of colors and well explained post. Next time add a link or video to your post to make it better. Other than that, great job.
ReplyDeleteGreat Job Shane. You did a good post! Your pictures were very nice! Next time you could maybe add a link or video.
ReplyDeleteGood job Shane. I like your pictures and I think you should put all the things needed like, the formulas and the square thingy (²). Good job.
