Answer:
divide perimeter by 3
Step-by-step explanation:
all 3 sides of an equilateral triange are equal, so you can divide the perimeter by 3 to get the length of one side
Given:
square based pyramid = 3.5 cm base
side length = 7 cm
Base Area = (3.5cm)² = 12.25cm²
Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
S.A = 61.25 cm²
L= 4*B+42
L= the load
B is the weight of each brick
42 is the weight of the carrier
Answer:
Perimeter = 30 cm
Step-by-step explanation:
10 cm x 3 = 30 cm
