<u>16 cubes</u> are needed to fill in the prism mad by the net.
<em>Sure hope this helps you</em>
(1,11/4)(2,25/4)
slope = (25/4 - 11/4) / (2 - 1) = (14/4) / 1 = 14/4 = 7/2
y = mx + b
slope(m) = 7/2
(1,11/4)...x = 1 and y = 11/4
now we sub and find b, the y int
11/4 = 7/2(1) + b
11/4 = 7/2 + b
11/4 - 7/2 = b
11/4 - 14/4 = b
-3/4 = b
so ur equation is : y = 7/2x - 3/4
1,159cm^2 that is the answer
