Regular quadrilateral pyramid with base edge b=55mm and lateral edge l=7 cm. Find the sum of all edges
1 answer:
Answer:
50cm or 500 mm
Step-by-step explanation:
A quadrilateral is a four sided figure. So, the base of the quadrilateral pyramid has four sides. It also has 4 edges and 4 bases
sum of edges = sum of base edges + sum of lateral edges
1cm = 10mm
55mm = 5.5cm
sum of base edges : 5.5 x 4 = 22cm
sum of lateral edges : 7 x 4 = 28 cm
22 + 28 = 50 cm or 500mm
