SURFACE AREA
Rectangular Prism
Rectangular Prism
= 2 (50 + 60 + 30)
= 2 (140 m2)
= 280 m2
Triangular Prism
Total Surface Area= (2 lateral area of rectangles + 2 triangles)
= 135 + 36 + 36
= 207 cm2
Cylinder
Total Surface Area= 2 (pi x r2) + (pie x d x h)
= 2 (3.14 x r2) + (3.14 x 8 x 12)
= 2 (3.14 x 42) + (3.14 x 8 x 12)
= 2 (50.24) + (301.44)
= 2 (50.24) + 301.44
= 100.48 + 301.44
= 401.92 mm2
