Step-by-step explanation:
Hello, there!!!
Let's simply work with it,
Firslty let's assume the whole cake, when you assume the cake in whole. you get,
length (l)= 16 in
breadth (d)= 6 in
and height (h)= 4 in
now, as it is a rectangle shaped cake,
volume of a whole cake (v)= l×b×h
or, v= 16 in × 6 in × 4 in.
Therefore, the volume of whole cake is 384 cubic inch.
now,
let's find the volume of eaten part,
As per the picture, the 1/4th part of cake is eaten so,
length = 8 in
breadth = 3in
and height = 4in.
so, volume of eaten part = l × b × h
v= 8in × 3in × 4in
Therefore , v= 96 cubic inch.
now, lastly finding the volume of remaining part,
v. of remaining part = v.of whole cake - v. of eaten part.
or, v. of remaining part = 384 in^3 - 96 in^3
Therefore, the volume of remaining part is 288in^3.
Hope it helps....
