Question

Help? Calculate the total surface area of the prism.

Answer 1

surface area=total area of rectangle

the base total Surface area

=(LW+lw)2

=(8×4+6×3)2

=(32+18)2

=50×2

=100cm²

surface area of a rectangle

4×12

48cm²

SA of another rectangle

5×12

60cm²

Sa of contact base

8×12=96cm²

sa of height rectangle

10×12

120cm²

Sa of another rectangle

6×12

72cm²

area of the top=3×12

36cm²

total area=100cm²+48cm²+60cm²+96cm²+120cm²+72cm²+36cm²

sa=532cm² is the answer

hope it was helpful.
