Find the surface area and volume. Answer with proper units. To represent m², use "sq m". Sample answer: 5 sq m. To represent m³, use "cu m"

#	Problem	Correct Answer	Your Answer
1		surface area = volume =
Solution The surface area is the area of the six sides. This is twice the area of the three different kinds of sides. = 2 × ((1cm × 3cm) + (3cm × 2cm) + (2cm × 1cm)) = 22 cm². V=lwh (length × width × height) = 2cm × 1cm × 3cm = 6 cm³.

2		surface area = volume =
Solution The surface area is the area of the six sides. This is twice the area of the three different kinds of sides. = 2 × ((1in × 4in) + (4in × 4in) + (4in × 1in)) = 48 in². V=lwh (length × width × height) = 4in × 1in × 4in = 16 in³.

2		surface area = volume =
Solution The surface area is the area of the six sides. This is twice the area of the three different kinds of sides. = 2 × ((8cm × 2cm) + (2cm × 8cm) + (8cm × 8cm)) = 192 cm². V=lwh (length × width × height) = 8cm × 8cm × 2cm = 128 cm³.
