Answer:
33,333 ft^3
Step-by-step explanation:
A pyramids volume can be defined by V=lwh/3. We know the base is 1000 ft^2, so we multiply that by an additional 100 for the height. We then have 100,000 ft^3. After that, we simply divide it by three, which is 33,333.3 repeating, and round it to 33,333 ft^3
Check the picture below.
ok, notice the volume of the smaller cube forming the larger cube. Keeping in mind that the larger cube has 90 of those small ones.
Answer:2 feet 4 inches more; 28 inches
Step-by-step explanation:
1 foot = 12 inches
12x4= 48 inches total
1x12+8 = 20 inches complete
48-20=28 inches
<span>a) 1 +2 +3 +4 +......+98
98 +97 +96 +95+......+1
sum 99 +99 +99 +99+......+99
there are 98 of these sums, the total is 98 * 99 = 9702, since this sum is twice the sum of the numbers 1 thru 98, we have
sum 1 +2 +3 +4 +.....98 = 9702/2 = 4851
b) 1 +3 +5 +7+.....+1003
1003 +1001 + 999 +997 +....+1
sum 1004 +1004 +1004 +1004 +..1004
There are 502 of these sums. the total is 502 * 1004 = 504008, since this sum is twice the sum of the numbers 1 +3 +5 +7 +....1003, we have
sum 1 +3 +5 +7+.....+1003 = 504008/2 = 252004</span>
