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
