What is the surface area of the solid that this net can form?

730 square millimeters
875 square millimeters
1,000 square millimeters
1,444 square millimeters

Option B:

Surface area of the solid is 730 square millimeters.

Solution:

Area of the rectangle = length × breadth

Length of the top net = (25 + 8 + 8) mm = 41 mm

Breadth of the top net = 5 mm

Area of the Top net = 41 mm × 5 mm

                                 = 205 square mm

Area of the second net = 25 mm × 8 mm

                                 = 200 square mm

Area of the third net = 25 mm × 5 mm

                                  = 125 square mm

Area of the bottom net = 25 mm × 8 mm

                                       = 200 square mm

Surface area of the solid = 205 mm + 200 mm + 125 mm + 200 mm

                                         = 730 square mm

Hence surface area of the solid is 730 square millimeters.

Option A is the correct answer.
