Peter stops a massive rock from falling on him using a tiny umbrella[]
I’ll use this calculator for volume
Peter Griffin is 5’10
Peter 96 px = 177.8 cm
Rock diameter 382 px = 707.495833334 cm
Divide that by two we get 353.747916667 cm plug that into the calculator we get 92712925.7 cm^3
Density of sandstone is 2.6 g/cc then multiply the two we get 241053606.82 grams or 241,053.60682 kg Class K
Lois lifts Stewie’s time machine[]
Let’s pretend this is a cylinder for a moment then divide that result by 4 since it looks like a quarter of a cylinder
Lois is 5’8
Lois 268 px = 172.72 cm
Radius 414 px = 266.813731343 cm
Height 28 px = 18 cm
The volume of a cylinder is π*r^2*h so π*266.813731343^2*18= 4025675.18578 cc
Divide that by 4 since it’s a fourth of a cylinder so 1006418.79644 cc
Density of steel is 8.05 g/cc
Multiply the two values and we get 8101671.31134 grams or 8101.67131134 kg Class 10
