#ProblemCorrect AnswerYour 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 × ((4yd × 1yd) + (1yd × 3yd) + (3yd × 4yd)) = 38 yd2.
V=lwh (length × width × height)
= 3yd × 4yd × 1yd = 12 yd3.

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 × ((1m × 4m) + (4m × 1m) + (1m × 1m)) = 18 m2.
V=lwh (length × width × height)
= 1m × 1m × 4m = 4 m3.

#ProblemCorrect AnswerYour 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 × ((8cm × 8cm) + (8cm × 7cm) + (7cm × 8cm)) = 352 cm2.
V=lwh (length × width × height)
= 7cm × 8cm × 8cm = 448 cm3.
#ProblemCorrect AnswerYour Answer
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 × ((2in × 3in) + (3in × 5in) + (5in × 2in)) = 62 in2.
V=lwh (length × width × height)
= 5in × 2in × 3in = 30 in3.
