Answer:
volume of the triangular prism = 105cm³
Step-by-step explanation:
to find the volume of a triangular prism , given the three sides to be 3cm, 10cm, 7cm,
so, recall the formulae for calculating the volume of a triangular prisim
volume of the triangular prism = 1/2 x a x b x c
volume of the triangular prism = 1/2 x 3cm x 10cm x 7cm
volume of the triangular prism = 3cm x 5cm x 7cm
volume of the triangular prism = 105cm³
therefore the volume of the trangular prism is evaluated to be equals to 105cm³
Answer:
10
Step-by-step explanation:
f(x) = 3x + 1
f(3)= 3 * 3 + 1 + 10
The formula for the volume of a pyramid is,
V=1/3Bh
Since the base of the pyramid is a square, the base area is 11^2
which equals 121 sq. units
So, substitute 121
for B
and 6 for h, in the formula.
V=1/3(121)(6) = 242 cu. units
Or alternatively 1/3(11^2)(6) = 242 cu. units

Step-by-step explanation:
8 x 6 = 48 because you just add a 1
Answer: 
Step-by-step explanation:
The area of a rectangle can be calculated with the formula:
l: the length of the rectangle.
w: the width of the rectangle.
The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
Knowing that the dimensions of the wall are 
by 
, its area is:
As they are planning that the dimensions of the mural be 
by 
, its area is:
Then the area of the remaining wall after the mural has been painted is:
