-- The Net
-- Top && Bottom
area of Top && Bottom = (Lxw)+(Lxw)= 2 (Lxw)
-- Front && Back
area of Front && Back = (hxL) + (hxL)= 2 (hxL)
-- Sides
area of the sides = (hxw) + (hxw)
= 2 (hxw)
-- Surface Area :
8+8=
2x8=
2(8)
area = 2(Lxw) + 2(hxL)+2(hxw)
-- Solve Surface Area
h=30cm
L=20cm
w=10cm
400 (2) + 1200(2) + 600(2)
= 2200cm(2)
-- Example Question :
-- The Net (for the example question)
-- Answer (Surface Area) := 2(Lxw)+ 2(hxL) + 2 (hxw)
= 2 (17cm+5cm) + 2(17cm+7cm)+ 2(17cm+5cm)
= 2x35cm(2) + 2x119cm(2)+2x85cm(2)
= 70cm(2) + 238cm(2) + 170cm(2)
=478cm(2)
