To see the measurements used below to calculate the area of the Net of the above solids, please
refer to the respective PDF file attached to the assignment. All length and area measurements are
in cm and cm2 respectively.
Formula for the Area of the Net of a Cuboid:
4(L*B) + 2(W*B)
= 4(8cm*4cm) + 2(4cm*4cm)
= (4*32cm2) + (2*16cm2)
= 128cm2 + 32cm2
= 160cm2
Formula for the Area of the Net of a Prism with Triangular Cross-Section:
3(L*W) + (W*B)
= 3(8cm*4cm) + (4cm*4cm)
= (3*32cm2) + 16cm2
= 96cm2 + 16cm2
= 112cm2
