Answer:
Surface area of box = 94cm²
Step-by-step explanation:
Given that:
Width of box = 3 cm
Length of box = 5 cm
Height of box = 4 cm
Surface Area = 2lw + 2lh + 2hw
Surface area = 2( lw + lh + hw )
Surface area = 2(5*3 + 5*4 + 4*3) = 2(15+20+12)
Surface area = 2(47) = 94 cm²
Hence,
Surface area of box = 94cm²
Answer:
x = 11
Step-by-step explanation:
8x - 8 + 30 = 11x -11
3x = 33
x = 11
Since they are similar, and a side of 10 = a side of 4, the ratio would be 2.5 : 1. You would do 6 * 2.5, which would equal 15, and (15 + 2) / 2 = 8.5 or 17/2
