Answer:
Therefore volume 'V' is given by V = 45 × 12 × 10 = 5400

Explanation:
i) given the formula V = l × w × h where V is the volume of a right rectangular prism and 'l' is the length of the prism base and 'w' is the width of the prism base and 'h' is the height of the rectangular prism.
ii) the length of the base 'l' is given as l = 45 cm.
iii) the width of the base 'w' is given as w = 12 cm
iv) the height of the prism 'h' is given as h = 10 cm.
v) Therefore volume 'V' is given by V = 45 × 12 × 10 = 5400
