If 10 skeins makes 4 scarves than if you multiply the skeins by 2 (20 skeins) it would make 8 scarves. There for dividing the skeins by 2 (5 skeins) it would make 2 scarves. So adding 20 skeins and 5 skeins you would get 10 scarves total
To find the surface area of the rectangular prism you do.
2(lw + lh + wh).
2((26*18) + (26*8) + (18*8))
2(468 + 208 + 144)
2* 820
the answer is 1640cm^2
