Cube (edge aaa): TSA =6a2= 6a^2=6a2, volume =a3= a^3=a3. Cuboid (l×b×hl\times b\times hl×b×h): TSA =2(lb+bh+hl)= 2(lb + bh + hl)=2(lb+bh+hl), vol =lbh= lbh=lbh. Cylinder (r,hr, hr,h): CSA =2πrh= 2\pi rh=2πrh, TSA =2πr(r+h)= 2\pi r(r+h)=2πr(r+h), vol =πr2h= \pi r^2 h=πr2h. Sphere (rrr): SA =4πr2= 4\pi r^2=4πr2, vol =43πr3= \tfrac{4}{3}\pi r^3=34πr3.
