Answer 1

Step-by-step explanation:

Base edge of the square pyramid = 16 cm

Slant height of the square pyramid = Height of the triangle = 10 cm

Area of the square = (side)2 = (16 cm)2 = 256 cm2

Area of triangle = 1/2 * base * height

1/2 * 16 * 10 cm square

= 80 cm square

Area of one square pyramid = Area of square + Area of four triangles

= (256 + 4 × 80) cm^2

= 576 cm^2  

Area of 500 square pyramids = 576 × 500 cm^2

= 288000 cm^2

= 28.8 m^2 (1 m^2 = 10000 cm^2)

Cost for painting for 1 square meter = Rs. 80

∴ Total cost of painting 28.8 m^2 area = Rs.80 × 28.8 = Rs.2304
