Answer:
side length a = 2 cm
Step-by-step explanation:
face diagonal f = 2.8284271247462 cm
solid diagonal d = 3.4641016151378 cm
surface area S = 24 cm^2
volume V = 8 cm^3
1) 4(3x+3)=3(5x+0.5)
2) 3.5
3) 54 units
2.52
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
