Answer:
114.3cm^3
Step-by-step explanation:
Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid
V = (1/3)(Base area of a square)(Height of the square pyramid).
V = (1/3)areahight
Area of the square
A = 7 x 7
A = 49
V = (1/3)49 x 7
V = (1/3)343
V = 114.(a repeating term)3
since we rounded
V = 114.3cm^3
Answer:
24 hours
Step-by-step explanation:
One member of the gardening club can alone plant flowers in 12 hours.
