Human surface area ft. volume

Human surface area and volume and

The head and the neck !!

Basically, we envisioned the shape as a hemisphere

The head and neck :]

The torsos

  • Torso chest to hip
  • Torso chest to up
  • Butt
  • Lower torso without butt

The torsos :V

Torso chest to hip

Shape: Trapezoid prism

Chest to hip

Dimension (cm):

  • Sides: 40cm and 35cm
  • Width: 12cm
  • Height: 18cm
  • Slant: 19cm

=> Lateral Surface Area = 1806cm2

Torso chest to up

chest to up

Shape: Rectangular prism

Dimension:

  • Length = 28
  • Width = 35
  • Height = 18
  • C arm: 36.5 cm > r: 5.8

=> Lateral surface area = 2487cm2

Butt

Shape: Hemispheres

Dimensions:

  • Radius = 7.5

=>Lateral surface area: 707cm2

Butt

Lower torse (without butt)

Lower

Shape: Rectangular prism

Dimension:

  • Width = 17
  • Length = 35
  • height = 15

=> Lateral surface area = 682cm2

The arms !!??

Arms and hands and fingers

We divided the arms up into four parts as below:

  • The upper arm
  • The forearm
  • The hand
  • The fingers

The upper arms

We divided this part of the arm as a frustum and with the measurements as listed below:

  • Top circumfrence: 23cm -> radius = 23/2pi ≈ 4cm
  • Bot circumfrence: 35cm -> radius = 25/2pi ≈ 6cm
  • Slant height ≈ 24cm

Therefore, our SA for this part would be 1/2 x (23+35) x 24 = 696cm

Then we times 2 for the other arm = 1392cm

The forearms ~~

As for this part of the arm, we also reshaped it as a

The hand

The fingers

Legs and feets and toes
