Presentation transcript:

Human body surface area Estimation and calculation

About this task  You will develop a simple mathematical model and practise estimation using standard units.  You will carry out calculations and compare the results to your estimates.

Starter: Estimation Estimate:  The height of the door (cm)  The volume of the cupboard (cm 3 )  The mass (‘weight’) of the box of books (g)  The surface area of the table (m 2 ) Once you have agreed and recorded your estimates, measure and calculate the values.

Main activity: Skin area  You are going to estimate the surface area of a volunteer from your group.  The volunteer must be willing to be measured and weighed.

Modelling the human body  The human body can be represented as a collection of familiar 3D shapes.

Results Suggested formulae 1. (DuBois & DuBois) 3. (Haycock) 2. (Gehan) 4. (Mosteller) Formulae are from Group Height H (cm) Mass W (kg) Est. Area (m 2 ) Suggested standard formulae 1234
