### Total Surface Area

The length of a rectangular prism are 4 cm and 8 cm and 1 cm. What is the Total Surface Area?

1st way:

L x W = A

Top: 8x1 = 8cm2

Top: 8x1 = 8cm2

Front: 8x4 = 32cm2

Front: 8x4 = 32cm2

Side: 1x4 = 4cm2

Side: 1x4 = 4cm2

T.S.A = 8 + 8 + 32 + 4 + 4 = 88cm2

The total surfce area is 88cm2

The leanths of a rectangular prism are 2 cm and 6 cm and 2 cm. What is the Total Surface Area? Use lateral area

LxW = A

2x2 = 4cm2

2x2 = 4cm2

^sides.

T.S.A = 48cm2+ 4cm2 + 4cm2 = 56cm2

Comment, if I did anything wrong or something. Thanks, byee
