Answer:
V = 8 cm³
Step-by-step explanation:
This is basically the formula for volume of pyramid:
Volume of Pyramid = 1/3 × Base Area x Height
OR
Volume of Pyramid = (Base Area x Height)/3
V = Bh/3
Given:
B = 4 cm²
h = 6 cm
V = Bh/3
= (4 x 6) / 3
= 24 / 3
V = 8
Hence
V = 8 cm³
If you want to represent this into inches simply divide 8 with 2.54 as
1 cm = 2.54 inches So,
8 cm / 2.54 cm = 3.15 in

Answer:
x=32
Step-by-step explanation:
sum of interior angles of a triangle = 180
add up all angles and equate to 180
(4x-13)+(x+18)+15=180
5x=160
x=160/5=32
x+18 = 32+18 = 50
4x-13 = 4x32-13 = 128-13 = 115
add up all to check whether ans = 180; 15+50+115=180

Answer:
-2
Step-by-step explanation:
-(4e+7)=1
-4e-7=1
-4e=1+7
-4e=8 divided both side by -4
e=-2
