The answer to your question is 365040000 lb or 3.65 x 10⁸ lb

Step-by-step explanation:

Data

Rectangular pyramid

base = 100 yd x 78 yd

height = 100 yd

weight of a stone = 468 lb/yd³

Process

1.- Calculate the volume of the pyramid

Volume = area of the base x height

-Substitution

Volume = 100 x 78 x 100

-Simplification

Volume = 780000 yd³

2.- Calculate the weight of the pyramid

                     468 lb 1 yd³

                         x      780000 yd³

                         x = (780000 x 468) / 1

                         x = 365040000 lb or 3.65 x 10⁸ lb

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
