All Formulae
Cube V = s³, SA = 6s²
Box V = lwh, SA = 2(lw+wh+lh)
Sphere V = 4πr³/3, SA = 4πr²
Cylinder V = πr²h, SA = 2πr²+2πrh
Cone V = πr²h/3, SA = πr²+πr√(r²+h²)
Pyramid V = b²h/3, SA = b²+2b√((b/2)²+h²)
Tri. Prism V = ½BH×L, SA = BH + perimeter×L
Hemisphere V = 2πr³/3, SA = 3πr²
Torus V = 2π²Rr², SA = 4π²Rr
