Answer:
25
Step-by-step explanation:
I got 25, because I worked it out and if you plug in 25 to the equation when adding all of the angles and making them equal to 180 degrees, you end up with the remaining degrees to be 25, leaving angle C at 25 degrees. I hope this helps.
Answer:
1,152,112.5 cm3
Step-by-step explanation:
To find the volume of this mailbox we can separate in two parts:
A rectangular prism, with dimensions 180 cm x 70 cm x 85.5 cm and
A triangular prism, with dimensions 25 cm x 70 cm x 85.5 cm.
Now we need to find the volume of both parts:
V_rectangular = 180 * 70 * 85.5 = 1,077,300 cm3
V_triangular = (1/2) * 25 * 70 * 85.5 = 74,812.5 cm3
Finally, we just need to sum the volumes of the parts:
V_mailbox = V_rectangular + V_triangular = 1077300 + 74812.5 = 1,152,112.5 cm3
