Question

*PLEASE ANSWER TY* What is the density of a 50-gram pyramid with rectangular base 4 cm x 8 cm and height 10 cm?

Answer 1

`(0.47 g)/(cm^(3) )`

Explanation:

→ First work out volume of pyramid using the formula
`(lwh)/(3)` where 'l' is the length, 'w' is the width and 'h' is the height

`(lwh)/(3)` ⇔
`(4*8*10)/(3)` ⇔
`(320)/(3)` ⇔ 320 ÷ 3 = 106.666666667

→ Volume of pyramid = 106.666666667. Substitute this value into the density formula

Density = Mass ÷ Volume

Density = 50 ÷ 106.666666667

Density = 0.46875 to 1 decimal place is 0.47
