Question

how do you find the surface area of a net of a box with the length of 20 the width of 10 and the highth of 12

Answer 1

Total Surface Area = 2(LW+WH+LH)

Explanation:

Surface Area of;

face 1 = LW

= 20 × 10

=200

face 2 = WH

= 10×12

= 120

face 3 = LH

= 20×12

=240

TSA = 2(200+120+240)

=560×2

=1120
