Question

AYO HELP ME OUT ASAP :(

Answer 1

122.7 cm³

Explanation:

Volume of composite figure:

Square pyramid:

a = 4 cm ; h = 4 cm

`\boxed{\text{Volume of square pyramid = $(1)/(3)$*base area * height}}`

`\sf = (1)/(3)*a^(2)*h\\\\ =(1)/(3)*4*4*4\\\\ = 21.3 \ cm^3`

Rectangular prism:

l = 6 cm ; w = 6 cm ; h = 4 cm

`\boxed{\text{Volume of rectangular prism = l*w*h}}`

= 6 * 6 * 4

= 144 cm³

Volume of composite figure = volume of rectangular prism - volume of pyramid

= 144 - 21.3

= 122.7 cm³
