• 2021 April(Z04) Math Question 28

    Perimeter, Area, Volume

    - Triangles, Squares, Rectangles, Circles

    Volume of Rectangular Prism
    Choice H

    Given that:

    L=7,h=6,w=5L=7,\quad h=6,\quad w=5

    Thus,

    V=L×w×h=7×5×6=210  cubes(white,black)V=L\times w\times h=7\times5\times6=210 \; cubes\quad(white,black)

    So the number of white cubes is

    Whitecubes=210×{1}{2}White \quad cubes=210\times\frac\{1\}\{2\}
    =105cubes=105\quad cubes
