Question

if one edge of the basebof a square prism is 7 cm and its height is 1.5 cm its total surface area is

Answer 1

A square prism has 6 sides.

Find the are of the top and bottom:

Area of top and bottom sides = 2 (Length x Length)

Area of top and bottom sides = 2 ( 7 x 7)

Area of top and bottom sides = 2 (49)

Area of top and bottom sides = 98 cm²

Find the area of the 4 sides:

Area of the 4 sides = Perimeter of the square x height

Area of the 4 sides = (4 x 7) x 1.5

Area of the 4 sides = 42 cm²

Find the total area:

Total surface area = 98 + 42 = 140 cm²

Answer: The total surface area is 140 cm²
