Find the surface area of a square pyramid with a base length of 11 cm and a slant height of 15 cm.
Find the volume of a rectangular prism with the following dimensions:
Length = 5 mm
Base = 7 mm
Height = 3 mm
142 mm3 ***
I agree with your first answer, but not your second answer.
Sorry. my answer for #2 was originally 105. wasn't paying attention.
Yes, 105mm3 is correct.
look at my answer to your first question here
In calculating the area of the triangle, the height is not 15.
make a sketch of the triangle to see that 15 is the hypotenuse.
