A2=a1*(-1)=8*(-1)= - 8
a3= (-8)* (-1)= 8
.....................................
a(n)= a(n-1)* (-1)
To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!
They amount to 168 legs.
Each spider has 8 legs; 8(8) = 64
Each cockroach has 6 legs; 5(6) = 30
Each bee has 6 legs; 7(6) = 42
Each deer has 4 legs; 3(4) = 12
Each cow has 4 legs; 4(4) = 16
The antlered creature will have 4 legs; 1(4) = 4
Adding all of these together,
64+30+42+12+16+4 = 168
