Question

Please help on 12&13 this is 7 grade math

Answer 1

For number 12, the formula would be

V= 1/2a • c • 10

Then you plug your numbers into the equation

a= 3

c= 6

h= 10

V=1/2(3) • 6 • 10

multiply the numbers and you should get that the volume is 90 cm cubed (Never forget your units) :)
