Ok this is a cake for me thanks for giving me the opportunity to eat it

Part A In finding the height of the box I first first consider the volume 2400 cm^2 with the means by which a triangle is calculated. In this case base*height*1/2. In this case that triangle is 3 dimensional. Therefore I consider the base which is comprised of 20cm*16cm=320cm^3 Now that we know the base, I use the formula base*height*1/2 to account for the height which is missing in this 3 dimensional figure. 320cm^2*x*0.5=2400cm^3 Now I isolate X 160cm^2(x)=2400cm^3 x=2400cm^3/160cm^2=15cm Therefore height of the triangle is 15 cm.

OpenStudy (anonymous):

Now that height of the triangle is known, approximate amount of cardboard required to construct this 3 dimensional figure is calculated as follows. For base 16cm*20cm=320cm^2 For rectangles constituting sides 2(20cm*17cm)=680cm^2 For the triangles 2(16cm*15cm*0.5)=240cm^2 Now that areas for all sides of the 3D figures are known, they are to be added. 320cm^2+680cm^2+240cm^2=1240cm^2 Therefore 1240cm^2 worth of cardboard materials are required to construct the figure above.
