Question

Salim bought a fruitcake, cut off a piece from it, and ate the piece. The dimensions of the cake before and after he cut it, are shown below. What was the volume of the piece that Salim ate?

Answer 1

C. 75 cu cm

75 cm³

Explanation:

Volume of the cake when Salim bought it = length × width × height

= 15 cm × 6 cm × 5 cm

= 450 cm³

Volume of the cake after Salim cut a piece = length × width × height

= 12.5 cm × 6 cm × 5 cm

= 375 cm³

volume of the piece that Salim ate = Volume of the cake when Salim bought it - Volume of the cake after Salim cut a piece

= 450 cm³ - 375 cm³

= 75 cm³

volume of the piece that Salim ate = 75 cm³
