So just keep subtracting 5 from three or do 5 times 20 - 3. that equals - 97
225/5 = 360/x
225x = 1,800
225x/225 = 1,800/225 = 8
It would take him 8 minutes
Answer:
12 will be the answer I think so
Volume of square pyramid = a^2 x h/3
Volume of pyramid A = 9^2 x 10/3
Volume of pyramid A = 270 cubic inches.
Divide volume of B by A:
1350/270 = 5
5 x 100 = 500 % bigger
To check, rewrite 500% as a decimal and multiply by the volume of A:
500%/100 =5
270 x 5 = 1350
This equals the volume of B, so the scale was calculated correctly.
