It is: 0.5*(5+8)*8 = 52 square units
2³, I believe.
7 and 5/8 = 61/8
1/2*base*height = area 1/2*8*5 = 20 square units
Divide by 8 and you get 3 with 3 left over. so 27 is written as 33 in octal (base-8).
4 5/8 = (4x8+5)/8 = 37/8
Positive 8 minus 5, also written as (8 - 5) is equal to three.
A Pyramind
A pyramid with a quadrilateral base.
5 and 3 eighths written as a decimal = 5.3755 3/8= 5 + (3 ÷ 8)= 5 + 0.375= 5.375
It is: 8*5*2 = 80 cubic feet
0.625 =5/8 =62.5%
