miskamm [114]

Answer:

volume = 195.52 in³

Step-by-step explanation:

given data

slant height of the cake = 10 inches

base length =  8 inches

solution

we know that volume pyramid is express as

volume = \frac{A^2\times h}{3}    ..............1

here

we use pythagoras for height

hypotenuse² = side1² + side2²    

put here value with other side is half of a square side

10² = h² + 4²

solve it we get

h = 9.165 in

so put here value in equation 1 we get

volume = \frac{8^2\times 9.165}{3}  

volume = 195.52 in³
