Question

Max wants to make an acrylic paper weight shaped like a right square pyramid, as shown below.



What is the volume of acrylic required to make the paper weight?

147 cm3

196 cm3

588 cm3

336 cm3

Answer 1

Volume of Pyramid = (1/3)b²h
b^2 is the area of the base
h is the height

From the given figure, the base is a square
so, the area of the base can be solved by using the formula for area of a square w/c is s^2
b^2 = s^2 = (17cm)^2 = 289cm^2


(1/3)(289cm^2)(12cm) or [(289cm^2)(12cm)]/3 = \[\Large196cm^3\]

Answer 2

thanks!
